A piggyback is an option but there are some things to keep in mind... mainly that the two ECUs have very different ignition advance maps... you're going to either want to pull timing across the board (a waste as it'll cost you low end power) or you'll want a piggyback which offers timing control or add an aftermarket timing system to the mix like the MSD 6.... The MAFT Pro is a piggyback which offers fuel control, timing control and boost control.

As for finding out which injectors, get the part number off of one... it's stamped in the black plastic part of the body.

Do yourself a favor and get a wideband sensor on there as soon as you can so you know you're not running lean. I'd recommend the Innovate Motorsport LC-1 as the least expensive option.... and it's a VERY good unit. (plus it'll integrate with any standalone system or the MAFT Pro)
