Hi Ryan,
If you get a GSO newtonian scope i'd recommend getting new springs (which sit under the mirror)
like these ones http://www.bobsknobs.com/Newt/page45/NewtPri.html you should also look at getting a collimation tool;
http://www.bintel.com.au/Accessories...4/catmenu.aspx i'd suggest either the Orion Collimating eyepiece or a
barlowed laser like the Glatter 1.25" Barlowed Collimator. I've heard its best to avoid the non barlow lasers.
I wouldn't worry too much about other eyepieces yet (you get 3 with the scope), perhaps a barlow lens or 2.5x powermate.
best of luck!
cheers
Russ
