The pfc is a good choice, you should get the datalogit also. I can't imagine using a pfc without the datalogit. You will also be able to use the fast reacting air temp sensor. See the thread in my signature.
(Here) The open element IATs allows much more precise tuning and a more accurate air temp table. If you do decide to go with the improved IATs you might see if Banzai will install a bosch connector on the IAT harness. The sensor uses the same connector as aftermarket bosch injectors so it shouldn't be a big deal for them to do. Or you could install it yourself, it's simple enough.

The injector driver works better then the resistors. The resistors only protect the driver circuit. It doesn't convert the signal, they also make the reaction time of the injector slower, which is why you should use the smallest resistor you can get away with. 1 ohm for bosch 1680's is probably ideal.
The injector driver minimizes injector "on time" and allows for faster response. This gives more control over the injector and allows for lower duty cycles and easier transition tuning.
In reality most hesitations caused by large secondaries with resistors can be tuned out. If you don't mind spending extra money on the driver box, and want the extra response then by all means go with the driver box. It's not worth the extra money for me though.
