using revolutionary to s-off should still work i think, read up on it and check your requirements.
then nandroid backup, change hboot to cm7r2 and restore.
don't use data2sd as sydbarrett55 has said. once you have enabled sd-ext and set it as default location, should have plenty of space for apps. you may want to increase your sd-ext size to around 1gb, though this all depends on how many apps you have and how much space they take up.
see my post above yours to read a bit more about where space is used...and install 'diskusage'
