You posted a photo recently which showed your jib clearly (atleast I think it was you). You need to pull the wrinkles out of your jib with some luff tension, then you need a little more rig tension (I think that was the topic of your last question). Both of these should help with pointing.

Do a search on mast rake in this forum, it's been discussed heaps before. The basics of mast rake are that it will not noticeably help pointing no matter what the rake is (ignoring extreme rake positions, usually negatively). What it will significantly affect is helm on the rudders(weather or lee helm) You want to set your rake so that you have a little bit of weather helm while sailing upwind (if you release the tiller, the boat will round up into the wind steadily). Not so much that it is ripped out of your hand. This won't help your pointing but will reduce your leeway angle, which is another aspect of achieving height while sailing upwind. (The angle of your sails to the wind and the angle your boat slips sideways through the water both impact your height and are tricky to distiguish between.)

There is nothing tricky or "mystical" about rake and pointing, it is all about balancing forces and moments generated by the sails and hull (including appendages).
