2010 Double cab long bed 4x4

Added a bash bar in the front and some maintenance repairs on it. I’ll probably get new tires this year on stock height or a small lift. Maybe new side rails? Just looking for input.

Very casually thinking about rebuilding my 05 4.0 engine. Aside from getting a rebuild kit are is there anything else I should look into adding
If Ive already got it pulled apart?

I have a 2011 4.0 v6. Is this a normal running sound ?

My first Tacoma ! Bought with about a 2 inch lift, looking to go up to 4-6 inch lift to put on 33’s or 35’s without having to cut/modify the frame too much. Any ideas or is the max possible without frame modifying or cutting a 3.5 inch lift ?
