For the Gmail app: DO NOT DO THIS WITH THE MARKET APP
The easiest way is with Titanium. Use it to change the app to a "User App" and then delete it. Go to the Market and reinstall it.
Another way is thru root explorer. Go into system/app, and then click the "mount r/w" button (to change the system files from read only to read/write). Then find the app, long press on it, and then hit "delete". Then push the "mount RO" button to change back to read only, exit out of root explorer and then reboot (this is important to get the change in system apps to "take."). When you boot back up, you should be able to install the app from the mkt, with the update.
For the Market App I think you are going to have to find the new market apk and put it on your sdcard and install it after having deleted the old market. Well, I would not actually delete it, I would rename it market.apk.bak. That way if the new market apk install does not work you can go back and undo the name change.
