integra386, good luck!
As to the 96 leds, why not, I also have integrated 6x3x5=90 in my red blade and 6x2x8=96 in my blue blade.
As to the resistors or not: for a red blade with serial II. technic (2 LEDs in series), you need the resistors, otherwise you will have a very narrow band to control your transistors -> effects will be less spectacular. Not to mention that not all small transistors can tolerate the power dissipated over them.
Better is to use a serial III. setup, then you do not need the resistors. 2.2V*3=6.6V, you only need to dissipate max. 8.2V-6.6V=1.6V over the MOSFET. If you insist on the serial II., then you need the resistors.
BTW, looking at your schematics, please do not forget the pull-down resistors from transistor gate to GND, otherwise you will have floating gate and you cannot control switch on/off (all LEDs will always be somehow in a random on state).
