Hi Dan, a warm welcome from me here in the south west.  Just a quick comment, I don't think the Telrad will be suitable for your telescope, it will be too big, the suggestion of the Rigel Quickfinder is a better one.  Clear skies!

Excellent point Robin. Slapping my forehead because of my stupidity. The Rigel would work much better!

Welcome to SGL Dan.

You'll find this place a fantastic resource and as you've already seen, everyone is very helpful.

Ref. your question on eyepieces and why you might want extra ones.  There are different types of eyepiece and some give wider views than others.  The focal length of the eyepiece and the focal length of the telescope determine the magnification.  A good 2x Barlow lens is also very useful for doubling the magnification.
