Loosen off collimation till they just grab a little and then collimate.... do the same with the secondary.
The easiest way to centre the focuser is a laser.....If you've got a mate who has one borrow It till you can buy a good one like a Howie Glatter Laser Collimator - 2"
Get one of these too:

Their easy to install ....this focuser hanging of the primary cell was a bad idea.
