For window regulators & stuff:
The regulators go out, but I am surprised to see 2 (two) failed motors for the regulators. The motors usually don't go out. You need 2 regulators, and could DIY it. You will save a ton of $$.
The 2nd bill has the light bulb socket? usually this fault is related to bad bulbs which fail to make good contact with the socket. I would try a different bulb (OEM from dealer, or an equivalent stainless steel coated socket) and clean the inside of the socket with fine grit sandpaper.
The 3d bill for sparkplugs - that's a trivial job, and I am surprised to see 3 coils (one bank?) go out. If this is the case, then you should find the root of the problem first. This might be due to a leaking VCG with oil in the sparkplug well, which you be able to see only after you remove the sparkplugs. I am very skeptical on the bust coils.
The 4th bill is a more labor intensive project, but not hard to do. It's the oil filter housing gasket and the CCV. The parts should bring you to around 120-150 bux for that one (the better ones - OEM, which you should use). The rest is mark-up & labor. In S Carolina you might not need the winterized version, but if you plan on driving for skiing trips, it won't hurt to have the insulated CCV.

This whole project you have if you DIY should take you 4-500$ tops and 1 day of work at the most. There are other areas of concern while in there, and I would check them out to be on the safe side (PS hoses, pulleys & belts, clean ICV, check DISA, inspect ALL rubber hoses and rubber caps, check thoroughly the cooling system to name a few).

BTW, if the O2 sensors were not changed, I would look into that as well. A bust O2 sensor might give some strange readings and combined with fouled up sparkplugs (oiled) could make you believe you have 3 coils busted.

just sayin'
