Cells normally dont pellet effectively in RNAlater. The best way is to just add equal volume of PBS to the solution and spin it...I normally do a 9k rpm for 3 minutes...
Its better to take a maximum of 1 ml per tube during centrifugation, else you end up with some cells over the wall which would be disturbed when pipetting the solution...Just to make sure, keep the supernatent and spin once more
Hope this helps

the ultimate goal is to use for microarray!
