You originally spoke of more cogs in back. You would need a new wheelset to do change to 9sp.
If you intend to keep the current wheels, awesome. That helps narrow the options in a good way.
You can keep of change your shifters. By the sounds of it, you could use some updates since there is skipping or rattling in a couple gears. A new cassette (freewheel?), chain, rear derailleur, and shifters wouldn't be very expensive for 7 speed.
Neat project
