Enjoy the new scope Tom!
I'd like to echo Malcolm's comment about not rushing. Play with what you have for a while and figure out which magnifications you use the most and what you like and dislike about the eyepieces you already have. Also, go to any scope gatherings you can and see what you like and dislike about other people's eyepieces (cheaper than having to buy everything yourself before you can play with it!). Everybody has slightly different preferences, e.g., I love lots of eye relief but many people don't care about that at all, and you only really figure out what you like best with experience. Clear skies sir.
