Help Freeing up phone space

[pvcprinting]

Since updating to 2.2 my phone keeps freezing but also alongside that i keep getting low on phone space message...so much so it wont allow me to open up my photo gallery

How can i free up some phone space....what can safely go

I would like to keep

along with my photos...which i would have thought would have been on the SD card

cheers
