1.) Chances are if you are satisfied with a Bose sat/sub system in your main room, you'll be happy with the JBL kit.
2.) But, the JBL kit is not a very good kit. Full range sats (no tweeter) and a limited sub. But >200 is not a big budget to work with.
For a bedroom and >200... go to Amazon and search MCS100. Going to be tough to beat that for ~$200.
SQ will be much better, though the sub is still limited it should be fine for a bedroom/small room.
