It's been awhile since I've torn apart any of my Titans, but *I BELIEVE* the digitizer and LCD have two separate flex cables. Replacing a digitizer isn't hard, but you can crack your LCD in the process (done it). Digitizers are pretty cheap, check eBay. You'll most likely need to solder the new flex cable, so be careful.

As for the keyboard, try finding a replacement keyboard on eBay. I purchased one for $20 after shipping and handling and it's working great after several months. The keyboard issues are common on the Titans, so I would expect any replacement keyboard to eventually show the same problems.
