Wj Question about injector size/fuel pressure in a stroker swap (WJ)

Picked up a cheap 01 Grand Cherokee in need of a motor and I plan on using the motor in the link below, it's a mildly built stroker, 258ci, was wondering what else I need fuel wise to run this setup, any help would be greatly appreciated. I'm trying to figure out if I need bigger injectors, adjustable FPR, and/or stand alone. I'm not looking to go nuts but just want more grunt than stock and reliability. What's my best bet with fuel and tuning? If I do get injectors and FPR would an average programmer be ok?

Here's the motor, picked it because it's basically EXACTLY what I'm looking for, not bad in price, and with a decent warranty.

It's only as strong as the stock zj v8's. Throw some 24lb fms injectors at it and call it good.

'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.

I had a 4.6 stroker XJ with 24 lb/hr and it ran fine (I think about the same horsepower than yours).
