If you have fairly limited funds but are having a remap and want some upgrades, then I'd suggest.....
1. Brakes - if you have more power you'll need effective brakes. I'd suggest on a limited budget upgrading to Cupra fronts (Same as R32, but red calipers

)
2. Suspension - If you can afford it, go for coilovers and ARB's. If not, at least uprate to something like Koni FSD's and H&R springs.
3. Extra associated power aids (but these can come much later if you wished) such as an air intake (or just filter), Exhaust, Forge DV etc, etc
The ED30 will be okay with just the remap on its own, but it is always better to uprate to balance the car back up again.
