the next big step, need some advice

Ok so heres my situation... Now that I have most of the stuff I need out of the way, its time to get on a dyno soon and do some serious tuning. My questions are, I already have a fmu with the stock ecu. What should I get to fine tune my fuel. I'm not trying to dump a grand into a ems or hondata unit. Other question is my timing, its still stock setting. Should I get some gears (belt is due to replace anyways) Obviously they would be doing all the adjustments and fine tuning. Let me know what you all think would be the best route to go...

get a greddy e-manage.....they should work right out of the box with honda's and you can reprogram them if you get the computer cable and sofware......i think they run for ~300$
