Hmm...
BattlingObesity.com (~18k Google results) would probably work best developed into a health information site, I don't think it would make much from simple parking. Something along the lines of this site:
http://obesity.battlingforhealth.com/ It sounds more like a "call to action" domain than a commercial site so I would consider grabbing the .org as well if you're looking for resale.
SimpleBeach.com (28k GR) I don't think would fetch much to a reseller because this term never appears alone. It only seems to be used in conjunction with an item or activity (simple beach wear, simple beach games, simple beach crafts etc.) and I can't find any place referred to as "simple beach". The word simple does have a lot of appeal though.
PremiumBreeders.com (1870 GR) This is your best one despite the low search results. That's because breeding (at least for dogs and horses) is a big money business. "Breeders" by itself returns ~19
Million results. Even if you lop off half of that for the band that's still a good showing. BTW "breeding" returns more than 41 million. You could develop this one with a simple directory script and sell ad space. Don't let this one go cheap.
QuitStalling.com (~24k GR) I see this a more of a political "call to action" domain than a self help site. QuitStalling.ca (the top ranking site on google) is a site protesting animal cruelty in Manitoba (I guess they don't like stalls...) but I don't see a lot of
commerical opportunity here. One idea would be to have a graphic designer make an appealing "quit stalling" logo and put it on cafepress.com for the major hot button issues of the day. "Quit Stalling on the Bailout", "Quit Stalling on Healthcare", "Quit Stalling on Green Energy". You could possibly lease it out during attack ad season to a party, candidate or PAC "Tell so and so to Quit Stalling on ..."
CurbsideAuto.com (~1300 GR) There seems to be quite a few businesses currently named "Curbside Auto" something or other (repair, glass). These types of businesses are kind of a hard sell to convince they need a good domain though.
I didn't give any dollar amounts because these all need development and what they will be worth depends on what was done so I thought I'd give you a few ideas instead.
Pretty good for a "newb".
