start by applying oil to each nipple where the spoke comes out and give it some time to penetrate, then wipe the surface off vigorously.
on the most bent area of the rim, only tighten/loosen maybe slightly over a quarter turn. then do the adjacent spokes less. use the valve (or its hole if you removed the tire/tube ) to keep track of going around the entire wheel. at the end of one circuit, squeeze the spokes together vigorously with your hands (wear gloves) all the way around and recheck, then repeat everything. actually, I usually start with the squeezing, too.
keep going until your calipers are not hitting/showing light through within reason (there's always at least a tiny bit, but that's ok)
if you have a flat spot in the roundness, that's a related procedure but the above is much more common.
if you do above, you will not fuck the wheel.
remember, if you twist the wrong way, you can undo it.
also, while twisting, pinch the spoke with your other hand's fingers. if the nipple is stuck and you feel the whole spoke "winds up" before the nipple gives way and turns independently, mark the turn you're going for from when it breaks free. then gently back off the turn to untwist the spoke; the spoke and nipple will usually untwist together, which is what you want.
