Hi flearosie ... i would love to buy that book
'The Dummies Guide to Maintaining a Dob' 
I am presently having a hell of a time trying to collimate my Dob - have been going through info on this site, and others.
Have a read of the info on collimation on a search, and good luck!!
If you have had the scope all covered up, then the mirror should be Ok, so it will just be the collimation, which may not be too bad either.
