 1. Don't worry about CFM so much, the tank can be the buffer for high usage tools. 
2. Get the 175 PSI models. I didn't, and I am still regretting it. 175 PSI will make your impact wrench AWESOME!
3. Two stage is pretty all there is for this pressure rating. The advantage is there's interstage cooling, and that keeps things much happier. 
4. The tank with periodic drainage is all you need. Unless you're spray painting, and then, you'll need something a whole lot better. 
5. 240 volt is always preferred. The motor will start more easily, with far less dimming of the house lights when it kicks on. 
6. There are some Craftsman compressors that are oilless at this pressure. That is about as low maintenance as you can get. Not super durable, but for the usage you're talking about, I doubt you'll ever wear one out. 

That's my input, your mileage may vary.

I am researching vertical tank compressors.  Won't be using it a lot,  but 
DO want it to be able to run basic air tools w/o gasping for breath and  
surely deal with wheel lug nuts.   Need to know max. cu. ft. per min.  @ what 
PSI should do the job.  Also, What is the difference between a sgl.  stage 
and dual stage unit?  I know I need a water separator and  filter.  Should it 
be 120 or 220 volts?  Prefer low maintainence, and  low money invested.  Not 
particularly interested in Chinese crap.
