Time to upgrade to HD TV?

I'm thinking about upgrading to HDTV. Currently we have a giant, 33" CRT JVC TV. I'm guessing it weighs 100 lbs. What I am considering:

• HD TV ... Our space is not large so perhaps a 38" LED TV
• A Blue-Ray DVD player with wireless
• A Roku streamer
• And upgrading our Comcast service to HD.

Any advice?
