Again, perfect info. Rang them up earlier and ordered the pads and discs for what I think is £47.15 inc VAT!
He said £21.25 for the pads and £19.75 for the discs, plus VAT...does that sound right? I double checked with the guy - I should be expecting 4 pads and 2 discs right?
Did you order them from a VW dealer or the TPS trade outlet? The discs retail (+vat) for around £45 each, and the pads £47 for an axle set (four pads) - but there are 'substancial' trade discounts on discs and pads - and those prices you've been quoted are the full-on trade prices - so make sure they stick to it!
And yes, you should get one box of pads with four individual pads, and two discs.
Ordered the pistol tool,
Which type did you order?
Had a look at those links for the anti-seize and silicone grease but nearly £50 on grease is gonna be a hard pill to swallow...
Do they do smaller pots? Are there any alternatives that are nearly as good in a smaller size?
I appreciate that they both seem a little expensive - but both will probably last a lifetime if you only work on your own car.
The reason I actively discourage 'copper' greases is because most which are available are neither waterproof, don't actually provide any 'lubrication' and very little 'anti-seize' properties once the solvent has evaporated, and the worse of the copper greases actually cause wear on the components they are supposed to protect from wear. There is also a 'cosmetic' issue with copper greases - they look horrible on cars with 'open' spoked alloys, though if you have steel wheels with plastic wheel covers, this won't be an issue. Nickel based anti-seize actually 'blends in' with unpainted brake calipers and alloy wheels.
Anti-seize pastes/greases can also be used (sparingly) where the disc 'hub' mates to the actuall bearing hub, and again on the roadwheels - where the 'face' of the roadwheel mates with the disc hub, the centering spigot ring, along with the wheel bolts - both the actual threads, and the conical 'seat' face. All these will stop something called 'galvanic corrosion' (basically were two different metals contact each other, then an accelerated corrosion takes place due to differing 'electrical properties') - and this is notoriously common with alloy wheels. Basically, any threaded fastener can be treated to a thin smear of anti-seize.
If you feel you can't afford the Nickel anti-seize, then the only copper grease I would recommend is the 'original' formulation from MolySlip - called 'Copaslip'. This is also available from Cromwell (same page -
http://www.cromwell.co.uk/static/publication/547/pages/1270.pdf), and is available in a 100gm tube at £2.70 plus vat (Cromwell product code: MLY-703-3100A -
http://www.cromwell.co.uk/MLY7033100A) - but you will probably see from the catalogue page the differences in prices between similar size pots of Copaslip, the Bostik Copper anti-seize, and the Bostic Nickel anti-seize. Anyway, the genuine 100g tube of Copaslip will be better than nothing at all, and also better than the copper greases you get from the likes of Halfrauds - and will hopefully be better on the wallet!
As for the silicone grease - the only other options are to get a tin of proper 'Lockheed Rubber Lube' - but this is very hard to source these days. The Rocol silicone grease also has many other uses - it can be used on plumbing systems, including drinking water supplies (such as tap washers, tap glands, etc), electrical connections (so any electrical connector on a car, including spark plug to ignition coil, ignition coils to wiring looms, and any other electrical connector you can find) - and is 100% waterproof. Sadly, I really don't know any other alternatives.
Thanks again for your help, really appreciate it.
Your'e most welcome.
Just because I'm the curious type, what cost difference are we talking about for an upgrade? Longer life, better performance? You've got until about 1pm tomorrow to convince me before I go for the VAG parts from TPS. 
Yes, uprated brake pads, larger discs, different types of discs (vented, drilled, grooved), braided hoses, uprated calipers etc. Some are just for 'show', and others are needed if you do track days, or drive the car very hard (and therefore brake very hard) when fully loaded (say on the Autobahns or in the Alps or Pyrennese). For 'normal' everyday driving, the standard brakes are normally perfectly adequate.
Cost-wise - well how long is a piece of string? It can start from around £60-80 for a set of uprated pads - all the way to £1500-£2000 for seriously uprated calipers, discs, pads, hoses, brake fluid, etc.
HTH
Oh, one other thing - you must only use Volkswagen approved brake fluid (if you don't, there is a serious risk of ending up with a £1500 bill for a ruined ABS/ESP unit) - so you might want to get some genuine VW brake fluid. 250ml can for £1.66, or next size is one litre can for £4.46 - but for a 'home user' I would not recommed the one litre tin - get one or two 250ml tins (due to brake fluid absorbing water from the atmosphere, once the tin is opened). Or depending on when it was last done, consider a full brake fluid change (should be done every two years).
