Build/fix 15 DC tundra

I have a 2015 DC with tuff country 4” lift, 33” Falken AT3s and “stock” 20” wheels. I’ll add a pic of current look.
If you look at my post history I still have that bad shock lol. I’ve also got a bad wheel that throws off everything and is destroying my tires.
I’m looking at fixing these suspension/wheel issues all at once. I don’t think swapping suspension now and wheels/tires in the following 6 months would be okay due to shake from that bad wheel. Would it mess up replaced suspension or should I stick with replacing it all at once?
I’m also curious if there’s better ways to go about getting what I need for what I’m trying to achieve. (I’m poor)
This is what my plan is:
2” drop kit from sos performance with front and rear bilsteins (to replace all current shocks)
17” Black Rhino Arsenals (black and tan)
33” Falken ATs again
Do I need the drop kit to achieve a 2f/4r drop? My local shop said only shocks…
I know it’s a big difference going from 4” lift to 2” drop but I want it for my dogs. Would those wheels/tires still work? I’m also very set on those particular wheels.

sorry for so many questions I need to get this sorted out the most efficient and economical way. Thanks guys!
