CRX HF tune up suggestions?

[McPatrick]

I am planning to have someone I know do a tune up for me and I was thinking of having the following done:

* replace transmission oil
* replace spark plugs
* replace cap and rotor
* replace ingnition wires

(oil and oil filter have just been changed)

I am wondering if anyone can make recommendations when it comes to the spark plugs and ignition wires. Also, can I still buy an original Honda cap and rotor or is it always going to be some other brand that makes it to OEM specs (I always prefer real Honda parts).

Also if anyone can think of something else that would be good to do to a CRX HF with 149K on the engine (and an unclear maintenance history), I appreciate the input.
