Hi mate, nice bargain you got there! Springs are all available as separates from anyone dealing with CML (ie LHS) but if you wanted internet route then
http://www.dcracing.co.uk/ or
http://www.m-k-racing.com/ tend to be good bets. I often find great stock at DMS aswell. Pinions are 48dp and again are all available from pretty much anywhere.
Spares I would recommend are front a-arms, front and rear shock towers and a rear chassis plate to be safe. AE spares are nice and cheap and should be no problem to get hold of.
The only other thing I can think you will need are wheels and tyres. The choice all depends on what surface you will be running on but Schumacher pins or spikes are a pretty safe bet! Hope this is of some help, welcome to the forum.
