As mentioned:
Joe Huffaker is good, but it depends on how much you want to do and spend.
Jon Becker can do almost everything and know where to get parts as needed. He has plenty of freinds, including Mike Cummings who used to race HP Sprites.
Jacque Andre at Bay Bridge Motors is also a good shop.
Don Racine of Mini Mania can be a good source for parts for the Bugeye.
Depending on the condition and what's there, you have plenty of options on performance upgrades. I would assume you have a 998cc series A engine. roller rockers, cam, head work (port & polish), upgrade the oil pump to a 1275 pump, the SU's can be tweaked and the intake ports and manifold polished, lightened flywheel and 1275 clutch,
brakes, brakes, brakes!!!!Front disc brakes, dual master cylinder, steel braided brake hoses,
exhaust header, high output coil, and upgraded distributor.
If you are not going to coil-over shocks, then consider heavier oil in the stock shocks, sway bars (front & rear). Nylon bushings for the A-arms, oil cooler, and a good fuel pump.
That's a start
