Advice needed on my build

I could use some advice planning out where my car is headed. I started a thread in the 2nd gen section, but this might be a better spot for it.

Here's a link

Here's a cut and paste of my OP also:

I'm trying to plan out a safe, reliable finish to my JDM 13B swapped convertible. Here's what I have so far.

89 convertible with a S5 13B turbo and transmission
N370 ECU with pins swapped on my N/A harness
TII driveshaft, diff and halfshafts
Airpump is removed and ACV is blocked off
Dual belt alternator pulley
N350 MAF on an Apexi cone filter with a 3-4" (can't remember the size ATM) custom TID. I've got a Cosmo MAF I'm trying to figure out how to create an adapter for. It won't bolt onto Apexi filter directly.

N390 Boost Pressure Sensor-mistake there, I actually have an N70 Boost Pressure Sensor

The N390 part is the OEM BOV (can't remember what the FSM calls it)

Greddy v2 boost gauge
Racing Beat REV-TII exhaust, turbo back
FCD
Koyo radiator but still using the clutch fan.

I know I need to focus on the fuel system and a wideband A/F gauge. I'm interested in Innovative's LC-1 or AEM's wideband.

Any opinions on either of those widebands?

I bought an FD fuel pump this evening. I've gotten advice to get either 720 or 850 injectors for the secondaries. Can anyone offer up some opinions on what size injectors I should be looking for?

With my modest build do I need to look into engine management or a boost controller?

That's all I can think to include at the moment. Let me know if more info would make advice easier.

I've been reading up on everything from wideband O2 systems, to fuel management, to boost controllers to stand alone and piggy back systems. I've got so many features and descriptions running thru my head that I've become a bit dizzy.

I'm leaning towards getting an LC1 and using either with no gauge or one of their digital gauges. But how much does that differ from the LM1? I know the LM1 allows you to record several channels of data. Can I also record my A/F ratio just using the LC1 and Innovate's software? Once I get into engine management and fuel management will the LM1 become redundant? Then there are boost controllers, is there a piggyback system or stand alone that will perform the same job?

Any kind of help sorting this out would be greatly appreciated
