I would use Rob from speedoracle... he's up in santa clarita, but he does great work and knows the NSX backwards and forwards...
8182231431 ... give him a call and get your timing belt done if it hasn't been done yet...
Here's what you should have done:
Timing Belt & Water Pump replaced
New AC and Alternator belts
New Coils and spark plugs and new O-Rings that go around the coils
Valve Adjustment
Oil change (goes with the TB job)
Check cam seals and plugs to see if they are leaking (common problem for high mileage NSX's)
Coolant Flush..
Thats all I can think of right now

Let me know if those things have already been done by the previous owner.
Good luck!
