Basically, there is no OC in Denver city limits but it's 100% legal everywhere else.
If you're not moving into Denver itself but rather one of the suburbs you should be okay to OC but make sure you figure out the Denver city limits. Somewhere on the forum are a couple maps of the lines, I don't have a copy though.
Carry in a vehicle is fine in any manner or mode, everywhere in the state...no permit required.
Places off limits to OC must be posted at all public entrances..usually city-owned buildings (and some land).
There aren't any restrictions regarding carry at places that sell or serve alcohol but it is illegal to be under the influence and carrying.
All the other "normal" restrictions apply: school buildings, federal property, etc etc etc...
