Ahh, I can give you the experiences of getting my old Lady back after 7 years!
Without going into the teeny details, and there was lots of expenditure which was 'unecessary' (ie: painting suspension, grinding off rust as and when I found it and repainting, replacing ok front shocks which would have scraped through another MoT or two, and so on)
Wishbonesrely on rubber, rubber decomposes, you may find after a few miles these 'crumble' a bit and your tracking's consequentially off. Unless you knwo these to be all in excellent order, worth changing the lot. (as droplinks etc can't be far behind)
BrakesCould be fine. Underneath, thorough check over. As I did, smear grease all over and massage into the lines. This isn't intended to hide rust from the MoT man, but preserves them and also shows the tester you care about your car. Hoses may be 'iffy' - check. Mine were all ok, changed the fronts, the rears are original GM from the 90s.
Coil pack / ignitionAs you state, you're doing this, good one
Rocker gasketsAs above, yes, worth it. I'd add get the breathers fully cleaned out. The car's not been driven for 2 years, so they've not clogged, but in doing them you'd be starting with a 'clean sheet of paper' so to speak.
TyresA hundred threads on here. Personally found Vredsteins and Enduros good. I'm running on old (matching, new, never used) spare wheels. All Michelin HX, there was a torrential downpour last night, and I 'tested' them on a quiet, empty road, well-lit road with not even a blink from the TC light.
BatteryI'm surprised this is still ok, but worth factoring in a new one (About £70)
Engine Vac tubes/elbowsAgain, rubber, you may find some bizarre hunting or bad idle issues, which is down to a vac leak, most likely here.
RemotesCan be re-synced by switching on ignotion, then pressing the lock button. No reason for them to have ceased functioning entirely, they should just need 'reminding' which car they are programmed to, worst case it's a trip to a Tech2 OOFer, but until then you always have the key. While you're at it, the Tech 2 can solve the airbag light, too
Factor in an oil and all fluid change, and fingers crossed you're about there.
Also, I can see you're on a budget, and the lower the £ helps you persuade the boss that the car is viable to be resurrected. So, as with all things, there's two ways to do things. For four tyres, exhaust, coil pack, exhaust (minus cats) cost me total of £163. The bargains are out there
