I don't see why you could not easily (especially with such a small room) simply go to the local hardware pickup a couple gallons of pre mixed concrete, take a big spackle type scrapper, pour some into your cracks smooth over, let it dry, simply go and get a really good (vapor barrier) type plastic foam that is used for underlayment for like the Cheap pergo flooring, than drop a thick carpet pad over that, and then carpet with a basic medium pile cheap carpet? I mean we are not really talking a very difficult thing here especially for the age of the building.
However not sure if you have any seeping or whatever under the garage walls that you will not end up with a soaked carpet acting as a sponge from the outer edges of your foundation.. In any case it would probably not cost much more than a few hundred bucks to do what I just listed..
Oh and yes it will sound Pretty Good!
I would put up some cheap absorbtion and diffusion products on the walls as well, it sounds like you might not even have drywall up yet, or if you do thats fine and just treat with some good bass traps or other foam products for studios possibly..
Other thing to remember is the garaged door, if its metal it will have some sound echo probably.
Are you putting in a Heating / cooling unit? If your gonna put any good gear out there, and furniture for that matter I would have a decent environmental control over the weather.. A projector, DVD player, whatever else will probably not like any extreme temps. Hot or cold.
If the floor is really un-level It will not cause you any sonic issues, however might not be good if it traps moisture or something.
