Jeff,
There are so many makes and models that will do everything you mentioned and much more.
Since the "point n shoot" types of cameras run from a little creditcard size (or smaller now) to fairly large SLR sized cameras, you need to put some of your boundaries on price, size, etc..
For good stillife (guns) photography, the little pocket cameras are a stretch at best and often leave you wanting for more. They lack the size of the optics and often the quality of optics(not always on that last point). The larger cameras have more glass (larger diameter lenses), permitting more light in and also dimensional abberations of the lens are less critical as the size increases.
The larger PnS cameras can rival the SLRs in terms of quality. These larger PnS cameras will often have more features and will do more than a higher priced SLR unless you have a pile of lenses.
Digital cameras come and go so fast these days that whatever you buy will be out of production shortly and superseded by something touted as better or having more features.
I have three digital cameras, a pocket size waterproof, a midsized PnS, and an SLR with a pile of lenses, external flash, etc. Frankly, just to post a closup picture of a feature on a gun, the 5 yr old PnS midsized camera is the go-to. It's much quicker to get it out and take a picture and get it on the bbs than the SLR. The little pocket camera just doesn't have the sharpness and is no easier or quicker.
I like the high end PnS Nikons, but some of the other makes look attractive too. Stay with a major brand you're comfortable with and you'll be in good shape. If you can find a camera show, you can handle a huge variety. Otherwise hit some camera stores and read some of the magazines for the latest greatest. With digital, most of us that purchased over a yr ago will only be able to tell you about a discontinued model.
I started a thread here a yr or so ago about flash techniques using a women's compact mirror and a PnS camera to get "bounce flash" pictures for soft lighting effect so sought after by most of the gun picture takers here. Here's a pic of the basic technique with the mirror and a white walled room, with an example from that technique and camera below it.


BTW, this pic is from my PnS with 'super macro' setting
