One very popular kit for the setup you describe is the Zone combination 4.25" lift:
https://zoneoffroad.com/products/425-in-combo-lift-kit-1997-2006-jeep-wrangler-tjCombine that with the RS5000X shocks listed for 2.5" (or 2") of lift and it will all go well together.
I have no experience with that kit, but have seen numerous people use it on this forum.
Another budget-minded option would be to combine the OME 2.5" suspension lift kit with a 1.25" body lift kit like the Savvy body lift kit. Avoid JKS and any other body lift kits that use a plastic puck. When the bolts are torqued to spec, the pucks squash and cause numerous issues. You'll also want a 1" motor mount lift with your 1.25" body lift.
Depending upon the final driveshaft angles, you may need an aftermarket CV style driveshaft, such as a Tom Wood (4xshaft.com) driveshaft. Unfortunately, with a stock shaft and stock (non-adjustable) control arms, a transfer case drop is unlikely to solve driveline angle issues in isolation.
