Don't short yourself with the compressor. So many times I've seen this because someone figures they'd rarely use it, so they get a tiny little POS that ends up being undersized and, therefore, virtually useless until it works itself to death. Impacts are moderately hungry tools, so you need as much tank volume as you can reasonably accommodate and afford. Belt-driven compressors are more efficient, fill faster, run quieter and last much longer than the oil-less ones. I got by for over 10 years with a Craftsman 30-gallon oil-less, but I worked it pretty good over that time. If you have the means, get a belt-driven 220V unit with a 30+ gallon tank. There are 110V units, though. Personally, I'd buy a good used "commercial-level" unit over a new oil-less if the price was right. Actually, during my compressor-hunting phase, I found a like-new 60-gallon Kobalt on CL. A motorcycle shop used it for a couple of weeks and then it wouldn't come on if it had even just a little bit of pressure in the tank. They were in a time crunch so they couldn't look in to it and they had lost the receipt, so they just bought another one to have a quick replacement. After popping off the belt and turning the flywheel by hand, I gave $200 for the broken one, figuring the compressor and tank was worth at least that. I later found this model had a batch of defective check valves that caused them to over-work and burn up the motors. A friend gave me a used 220V compressor motor he had laying around and I bought a new check valve off Amazon. For under $230, I have a like-new $500 compressor:
As far as what brand of air tools, I can't really suggest anything in particular. I have an old Ingersoll-Rand 1/2" impact that was given to me. It works, but seems to struggle on things that I think it shouldn't. I'll invest in a new/better impact one day after I've researched them. I hear the HF impacts are sturdy performers for home use and would probably be just fine for you to get set up.
Bonus/pertinent story: I came home one day and the circuit that oil-less Craftsman was on had a tripped breaker. I reset it and it immediately tripped as long as the compressor was plugged in. After inspecting it, my guess is that it had a slow leak and would kick on intermittently, but the pressure switch failed and it didn't shut off at it's set pressure and burned itself up. Other than that, the tank was in mint condition so I bought a 110V motor off CL, a twin cylinder compressor from Harbor Freight (solid units for the money!), some copper tubing and fittings from Home Depot and Frankenstein'ed it into a much better compressor for the garage. I could've used a 220V motor, but I already had a 220V compressor for the shop so I wanted to have a portable 110V unit for the garage that could be taken somewhere if needed:
