Should drywall used in a ceiling be of a different weight/grade than drywall used in walls?
We are demoing a closet this weekend, and will need to repair the remaining drywall in a few places.

Personally I would pull them down and drywall the entire thing. The edge of cabinets is going to not look very well when your done if you don't and will stick out like a sore thumb. It's easy enough to pull down the cabinets too.
Also I would remove the drywall from the edge by the wall too and mud the corner. It's going to make it cleaner looking in the end.
Ideally this should be screwed/anchored into a joist for maximum support. However, if you really want to use a drywall anchor, you should use a toggle bolt or a ceiling anchor. Instead of just screwing into the wall, these expand to several times their size which gives you a good hold, especially when the force is pulling directly down. 10lbs might be pushing it though, it will depend on the thickness of your drywall and the overall condition. The worst case is you just have to patch the hole and repaint; drywall is pretty forgiving like that!

Depends on the ceiling/wall function. In most cases for repairs you want to replicate what was there, unless you are ripping the entire wall/ceiling or it's too hard to track down matching replacement drywall.
If the wall/ceiling is a firewall, you normally need to replace the structure that was there, which may be double-layer 5/8 type X ("firecode") gypsum. I prefer it for ceiling applications anyway (single layer where double-layer is not needed), as it's far less prone to sag than the thinner grades. It's also heavier, which you may not be fond of - and it is sometimes used on "acoustic" walls for that reason.
I've dealt with old walls that use as little as 1/4" drywall. 1/2" is what's normal/standard in new construction - 1/4 and 3/8 may be available from a supplier but I would only use those for repairs of a wall starting with that thickness where replacing the whole wall doesn't make more sense.
