Whatever is a good price because whatever you have will be much bigger than you need, 40GB is probably the smallest you will find new. If you want to run some other things maybe bigger is useful?
The database will be much quicker when it's on a separate drive to recordings so even a 4200rpm is probably good, 5400 is the normal though. I would get a single platter drive (9.5mm) as they are usually cooler and quieter.
MySQL guys don't recommend XFS for database files, EXT3 is a safe and reliable (well proven) bet, "I" wouldn't go with EXT4 just yet. H'mm my database files are on XFS, maybe I should change that!
I would put the OS install and everything except mythtv /recordings on the new drive, then it's also possible to spin the 1TB drive down when there are no recordings or playback, there are always some logs writing or something. My slave backend/ frontend does this because it is in the living room, also it is quieter because the database is on the master backend in the office, I also send logs remotely so there is very little disk activity other than recordings.
