make sure the check is off in activesync for whatever it is.

i am seeing more and more issues with unlocking. unlocked a friends tp1 and ran into the 202 error. what i ended up doing was reformatting my sdcard and flashing from there. i had to reformat the card for it to read. have you tried via the sdcard yet? and if so were you told that the img file was not found? a format will fix this.

lastly, no once you unlock it and flash a custom rom, you will not need to relock. you only need to relock when you have to send the phone to sprint. then you will want to reflash a stock rom and lock it.
