Questions about Turboing my ngc

[Craz1000]

im throwing an srt turbo on my 05 sxt. im thinking about a RRFPR rather than going with megasquirt because i want the oem computer to keep control of the car instead of me controling the car, i dont know enough about this setup and tuning the car electrically, plus i know people that have baught MS kits and have had some serious downtime getting the bugs out, unfortuneatly this is my only car at the moment and downtime is something i cant afford at the moment, when i get another car then ill throw in the MS setup. i read the above post and i wanted to see if i got this grocery list right

SRT manifold adapter
RRFPR
Map Clamp (where do i get this from?)
varius lines for collant and oil for turbo(have any suggestions on where to hook these up or products that would make this easier?)
i already have a wideband
stage 0 srt injectors (are these the factory srt injectors?)
better oil pump

i just have these questions/ issues
the RRFPR dose this work inline with my fuel pump or dose it replace it

i know the ecu is gonna have a fit when the mixture enriches from the RRFPR is this going to be an issue, how did you deal with this problem since the ecu is almost always in closed loop

now i am also assuming the 420a can take the boost from the factory srt turbo, i know the stock insides max out at 260hp before stuff starts breaking, so i should be safe especially since im either keeping the stock intake manifold or using the magnum manifold
