new lens for glamour photos??

would you suggest a 17-40 L or is my current lens list good for glamour photography.

If you plan on doing studio glamour then consider a prime, possibly the 50 1.4 or the 85 1.8. How much room will you have to work with? You might need something wider, like the Sigma 30 f/1.4 or the 35 L if you want to spend some big bucks.

its going to be an extra bed room in my house. i want to stick w/ only canon. so the 50/1.4 is a good idea?

50mm F1.4 on a 1.6X camera is quite long, I often use my Tamron 28-75.

Depending on how big the bedroom is and how much you want to get in the shot. If you are only doing headshots or partial body, then the 50 would be a great choice. However if you want full body shots then it might not be wide enough. That 17-40 might be the way to go or again you could go for the 35 f/2 or the lovely 35 f/1.4 L.

Definately a prime. Remember the people who do these types of shoots usually aren't hurting in the "beauty dept" so, they won't mind showing it all for the camera. A nice sharp prime won't hide anything!

I'd suggest you take your kit lens and adjust to 50mm and then to 30mm to see which would suit you the best. For a bedroom the sigma 30mm f/1.4 might just be your best candidate, but if you you've got the loot shoot for the 35L I've heard nothing but good from it.

what about the 28/1.8?

If I had to choose between the 28 1.8 and Sigma's 30 1.4 I would take the Sigma. I know you said only Canon, though. On FM, the 28 1.8 gets a 7.7, while the 35 f/2 gets an 8.8. Canon's lenses below the 35mm mark start to get a little weak. I would stick with the 35 f/2 if that focal length is wide enough for your room.

I use the 35 f/2, 50 1.4 (or 1.8), and 85 1.8 (but use this for tight head shots). Sometimes I wouldn't mind a 17-40 just to get a little wider, but my kit lens does fine for that when stopped down.
