If you want to shoot in low light, you need F2. The Canon 35F2 IS was my choice on crop and later on full frame. F2.8 may be a problem when lighting gets low, unless you are on full frame, but F2 is still desirable.

The older 28 may be sharp in the center, but you will need to stop down to get the corners OK, at least according to reviews. I would recommend the 35 F2 IS. It is an excellent lens for your needs. If you think you will be going full frame in 10 years, it might be silly to only buy full frame lenses. However, if you know what the time frame might be, and it is short, It is a different story and it makes sense to avoid putting lots of dough into crop lenses. If you are OK with F2.8 then don't rule out the new Canon 35 F2.8 macro lens.

For shooting in low light, I prefer at least F2. This way you can keep shutter speeds up for people photos. Fast AF is also a help, and you get that with the Canon 35.

Also, unless finances force it, you don't necessarily have to get rid of a crop camera and lenses when you go full frame. There are lots of times when I still use a crop body, since this gives me additional options with field of view.
