Trd OFFROAD suspension, help please

I have a 2015 with the OFFROAD package and I'm kind of shooting for a trd pro replica. Love the looks and stance of those things. Plus I think mine sits to low for a 4x4. So a few questions for anyone that has one or anyone who may know

1. I'm not gunna shell out a ton of $$$$ for the actual setup, but how much lift do those things have up front?

2. Is there any lift at all in the rear at all? Looks like they sit higher than mine and I have the 3+1 leaf pack

3. Anyone know the cheapest place to buy the black beadlocks new? Also will the tpms from my trd OFFROAD wheels work on the new wheels?

4. How big off a diffrence in stiffness will there be in going from offroad (progressive) coils to the 884 coils? I hate how the stock setup dives when I hit the brakes and how it has so much lean when cornering. If the 884's aren't much stiffer, what are some other Coil options for no more than a 2" lift? I don't wanna shell out 400 for uca's.

So far from what I can gather it seems I can do 5100s with 884s up front and a 1.5" AAL in the rear. Or a 1" block + the black trd beadlocks and I should be pretty close to the pro. How's that sound?
Thanks in advance guys
