I would say start with a prime (50mm is the cheapest and most popular because it lends itself to many situations), then a 70-300mm to cover distance and then worry about an ultra-wide (10-20) which is going to cost more than the previous 2 lenses combined.
Don't forget to add a tripod, otherwise that remote is pointless.
And then if you want add a flash.

You don't want to be ATGNI.

nothing wrong with going for the 35mm, 35mm on an APSC crop ~ 50mm

'The 50mm lens is called a "normal" or "standard" lens because the way it renders perspective closely matches that of the human eye. Consequently, images made with a 50mm lens have a natural and uncontrived look. This is the lens that likely would have come with your camera had you bought it 10-15 years ago.

a 50mm lens on an APSC body actually gives you a 75mm lens which will flatten objects down.

Future Developments (In Order):

1, 10-24mm
2, 35mm Prime
3, 70-300mm
4, Graduated Filters

Based on ATGNI principles, I'm trying to be conservative.

Nice list, if you can afford it get the 10-24 before you go away, assuming you've going to Tunisia to see the country and not for the sun, it will be a great lens to have with you.

I was about to query the 50mm choice on the c sensor.... I know some people still favour it, whats ya thinking dubfan?

Sadly it's a seriously short notice trip for three nights, sun chasing, but this does afford me plenty of time to go off shooting whilst the gf sits by the pool.

Mosque's, Souq's, Kasbah's, Medina's  and beaches. yum yum!

May go back at some point, quite fancy trying to find that second sun on Tatooine.

My original reason for going for the 50mm f1.8 prime was that it was the cheapest way to get a prime with good glass and a lower f-stop. Also 50mm is equivalent to 80mm on film, which is a good portrait length.
I now have a 28-70mm f2.8 which gives me a 44~112mm 35mm equivalent. This is now my preferred lens for most uses. (Although I'd quite like a 24 or 30mm prime too)

It's all down to what sort of photos you want to take. If you're just starting out, the wide end of your kit lens will suffice for a while, but it obviously only goes to 55mm which leaves your long shots uncovered, hence why I would go for a telephoto before going ultrawide and a reasonable telephoto 70-300 will be cheaper than the ultrawide.
But if you have plenty of money to spare, then sure go get an ultrawide. If you don't use it, you can always sell it.
Personally I'm currently aiming for a 70-210 constant f4 telephoto lens because I'll use that more than a 10-20mm (which is on my list), but it's down to personal preference and the type of photos you take.

Good good, I'm on the right track, wide angle lens it is! :-)

I got a 10-20mm when I got my 500D a couple of years ago and I have used it SO heavily.

While I back up the 50mm prime recommendation I cannot temper the enthusiasm for a good wide-angle lens - they add a LOT to your pictures out of the box, because the images are so cinematic, just be careful shooting at the widest end of the range as you will get barrel distortion of the image.

Rubbish. Hope you can claim it on insurance.

Certainly going to put in a claim, still somewhat shocked about it tbh.
