About which lenses will and won't mount on an FE2 - they simply need to be AI or newer, so AI, AI-S, AI-P, AF, AF-D, AF-I, and AF-S.
AI lenses are manual focus, AF lenses are autofocus. AI-P lenses are denoted by a P after the aperture number in the designator, i.e. 1:2.8P. AF-D lenses are denoted by a D in the same place as the P above.
AF-I and AF-S lenses may also be AF-D, in which case they'll be marked AF-S Nikkor 1:2.8D or something like that.
As a caveat, watch for G-type lenses (look for a G after the aperture number). These lenses will mount on the camera, but without modification will shoot only at minimum aperture. That said, modification is quite simple and non-destructive.
Also watch for Non-AI lenses, as mounting these will damage the camera. These can be generally identified by the metal fluting on the rings, as opposed to rubber on AI versions. Some such lenses have been converted to AI though, and you can usually tell by looking at the little ears at the 5.6 position on the aperture ring. If they both have a little hole cut through them, on either side of the gap in the middle, it's probably an AI lens.
Other than that, any lens mounted will function fully.
I bought an FE2 about 2 months ago now, on a whim as well. I've been eyeing off an 85 or 105, but for now I rarely remove my AI 35/2. Being in the middle of the whole 28/50 thing, I think it offers a good compromise of width, price, and size.
Whether you buy an FE2 or FM3A, you won't be disappointed by the precision feel of the camera, the silky-smooth wind, the comfortable bulk of the copper-silicon-aluminium body, and the fabulous quality of the lenses.
Oh, IMO, the silver bodies look better. The black is a novelty, sure, but the silver just has that vintage charm.
The bokeh is wonky at times but still kewl!
