There are a LOT of things you can do - besides working a bunch of overtime to fatten up the bank account...
Disassemble and refresh all of the suspension and brake systems with new bits - CV joints & boots, rod ends, caliper seals, wheel cylinders, bearings, etc. You have to use stock pieces, so they can be purchased with confidence. Don't put anything back together until you have sourced your suspension components and don't buy anything there until you know the book.
Take care of bodywork issues, remove insulation goo, make sure any rust is mitigated, figure out which panels need to be painted - get that done and rub out those that don't.
Get a factory manual and read it. Figure out where all of those wires go!
Spend some time spooking around recycling yards to find missing bits and a replacement tail light assembly.
Work on a good deal for a new hood.
Get in touch with anyone in your region or division running an ITA Honda and volunteer to help out at the track, prepare the car, and so forth.
Find a certified Honda mechanic and weasel your way into his/her life. Ply with food and alcohol if necessary.
And finally, DO work those overtime hours. You are several thousand dollars from getting on the track and every little bit helps.
Have fun!
