There are a couple of options on live centers. I have a Oneway, which is very nice, but also very pricey (about $100). Nova makes a similar system, but it is almost as pricey, if not more so, depending on the vendor. Each system features different attachments to the basic center which expand its capabilities. I am about to purchase a Pro center from Woodcraft (about $50) to replace my cheapie Jet center, which is about to go belly up. It is more basic that the two mentioned above, but offers interchangable points and is bored through. I am buying it for the bored through feature. If I was starting from scratch, I might buy the Nova and skip the Oneway, but since I have not seen it in person, I would hesitate to recommend it on the strength of seeing a picture.
Buy a separate faceplate. A 4" diameter will be big enough to hold anything your lathe will spin, and faceplates can be used for a number of different things, allowing your chuck to be freed up. One nice thing about starting a bowl on a faceplate is you can check the tenon you turn to see if it will fit the chuck before you remove it form the faceplate. If your faceplate is affixed to the chuck, you lose that advantage. You can also use a faceplate for single purpose wooden chucks, such as a custom mandrel or a comreession chuck for turning the foot off of a bowl.

Just yesterday, we used clamps after glue simply to take the bow out of the wood we were using, and it straightened everything out for us. Usually though, any time you lay up a project the clamps are...
