These are my thoughts, i have no tuning experience yet, so take them for what they're worth:
You might as well go with nistune. I hear time and time again that the stock ECU is great for controlling the engine for what 95% of the guys on this board are capable of financially.
It's something like $4-500 with license and board so you really can't beat the bang for the buck. Get a wideband and some sort of knock sensing device (you can wire the bosch ones with a resistor in line and listen thru your laptop) and then you'll be well on your way.
If you goto the nistune site they have a nice beginners guide to tuning. There is also a massive thread on factory ECU tuning on SAU. I've heard of lots of guys learning from scratch, but they all have things in common: they researched, had proper monitoring equipment, took their time tuning, oh and took their time tuning.
Good luck.
