Buick has punched holes in the rear of the car, behind the bumper.
These hole were covered with a tape to prevent water from getting in. As car ages the tape comes loose and the spare tire well fills with water.
The rear bumper has to be removed to get access to the holes, for you to cover them. I recommend that you use Extreme Weather Foil Duct tape to cover them. (available at Home Depot)

Water leaking from plugs on bottom of gas tank

That makes no sense whatsoever. If water were coming out of the fuel tank, so would fuel and the car would not be driveable in that condition. What you are thinking is the fuel tank may well be the bottom of the trunk. The spare tire wells in most trunks have drain holes in case water gets into the trunk. This is more common than you think. The gasket that seals the trunk lid often gets loose over time and allows water intrusion. The water finds its way to the spare tire well and drains out.

2008 Buick Lucerne...water in spare tire compartment

to fix this problem with my 2007 buick lucerne I had to take off the bumper and then remove the old seal on the body under this bumper and reseal it. it was not the trunk seal and nor was it coming from the lights or anything else. it was this seal that you cannot see unless you remove the bumper.

2007 buick lucerne w/sunroof water under rear seat

Not really., because the leak could very well be coming from the top or sides of the window and just running down,
Call around to glass shops and explain they'll be able to give you a estimate. Also you could take to a nearby body shop and have them confirm your suspicions.

Water in the trunk, and under the back seat. under the seat may have come from the spare tire well being 75% full of water. Where do I look for the most obvious leak

tail lights. you may have to get into trunk with a flashlight and have someone with a hose pour water near the lights and see where its coming in at. look for water stains,

Noise in front end when going straight or turning right. Noise stops when you turn left.

i would check the right front wheel bearing . Jack the right side up and feel the tire pull back and forth and see if the tire feels loose if it does the wheel bearing is junk. only other thing check the cvc axel.

2007 lucerne has water in spare tire wheel well

This could be coming in from a number of areas. The seal on the rear window, the rear lamp seals or the trunk lid seal. Empty out the trunk, remove all moisture and finally dust with baby powder. Now spray your car simulating rain, for about 15 minutes. When you open the trunk you will be able to trace the cause of the leak by following the runs in the powder. All you then need to do is seal the ingress and retest. Clean out all the powder when finished, leaving it all scented and not smelling of wet dog. Hope this helps...Please vote for me.
