BLiTZWiNG,
Few words of about collimation at the business end of the job (...or how not to make things much worse than you have to):
With the secondary you probably only need to tweak the three collimation screws (not the middle one), because the position of the mirror along the length of the tube should be OK. These you should adjust in small steps (less than 1/4 turn!) otherwise the mirror could loose its support. In each step you loosen one screw slightly, then tighten the other(s) to take up the little slack.
Adjustment of the primary wasn't clear to me at first, because I was expecting to see only 3 screws not 6. It is a lot easier than the secondary though, because the mirror is always well supported by 3 springs loaded screws at the back of the mirror. There are 3 other screws flush with the back of the mirror housing. Loosen these first, then adjust orientation of the mirror at the 3 spring loaded screws, finally retighten the mirror housing support screws.
Hope you and I both get some breaks in the clouds. Despite all us Victorians buying all that astro gear, I remain optimistic. Have the dew patrol ready! Resist the temptation to use the eyepiece holder on the side of the dob mount!
