A bee vac in not really a necessity (how did beeks of old do it before vacs). I call my bee vac crowd control, just gets the masses out of the way. Without the vac you will need to work just a little slower, smoke will move bees very well as will a little shake of the comb.
Yes you can just cut the combs off and rubber band into frames, be sure to keep the comb oriented in the up direction.
This late in the year you will need to feed, feed, feed!
Check them in a week to see if there are any eggs (if you can not locate the queen when you do the cut out), if not consider doing a combine with a weaker hive and then split them in the spring.
