I would just carpet the basement.. Get a quality pad that has a vapor barrier built in and call it a day... Most retailers install the carpet for free if you buy it from them, don't get suckered into buying the more expensive stuff because it has a "better warranty".. Most homeowners replace their carpets every 5 to 10 years, so that lifetime warranty is just a marketing scheme... Plus if you do not plan on living in your home for a long time then the ROI on the more expensive stuff isn't there..
For the spots that are uneven you can run a grinder with a cup wheel over the high spots and leave the low spots alone (as long as they are not craters)..
For the bulbs, there should be no reason they are charging you more, unless they already ordered them and they are charging you a restocking/reorder fee.. Personally I would stick with the warmer color (Soft white) as daylight bulbs are harsh and produce a fake "daylight" color (especially LEDs)..
