You can walk around central Denver easily. If you stay downtown or West across the river, it is an easy walk to the arena.
There is a free bus that goes up and down the main boulevard downtown (16th St). It can take you right up to the State Capitol.

Skyride shuttle from airport to downtown only $11.
Lots of nice pubs across the river in LoHi. Great Mexican food everywhere.
Coors Field is beautiful.
