Collimation Confusion

Hi guys,
Its me again with yet another annoying beginners question. Firstly i need to give a bit of background on my scope as i'm not sure if this is relevant.

I own a Saxon 8" Newt, it had one of those really bad R&P focusers on it, i put up with it for quite a few year, but last year i had enough and i purchased a bintel crayford style focuser. I had some slight problems fitting this focuser to my telescope but with some new screws, some grinding in the screw holes and a bit of frustration i managed to get it focused.

Around this time i also learned more about collimation. I purchased a laser collimator and have had a couple of goes moving the secondary mirror only. Today i have got the guts up to start moving around the primary mirror to see if i can improve this further.

My question is, how important is the focuser's position in the telescope, can any mis-alignment be collimated out?

Also, should i be playing with the primary mirrors position with only a laser pointer? If so what exactly am i looking for with the red dot?

Thanks for your help guys
Scott
