Welcome to the club 
if you want to document a design on perf board (which is usually what I want to do) I suspect you are better off using the breadboard view than pcb. that may not be correct in your case because you appear to want to use both sides of the board and as far as I know breadboard doesn't support that (but then I'm a newby too). It will however let you click on a resistor lead and drag it the appropriate number of holes and happily extend. If you enter breadboard view and delete the breadboard (by selecting it and hitting the delete key) you can then hit the core parts menu and drag in a perf board (or strip board) from the breadboard view section near the bottom and do your wiring on it. For documentation purposes (because I expect the wiring not to work correctly!) you could put two side by side, one for the top and one for the bottom (as noted schematic and pcb views are likely to not be happy about this though).
