I'm not sure I'd spring for TeleVue eyepieces for a first scope, especially not for a $700 Nagler! I'd probably start with a set like a 15mm, 20mm and 30mm (or 42mm) GSO SV, and their ED 2" Barlow. They perform well on an f/6 telescope (which yours presumably is) and are all comfortable to use.

The true field of view depends directly on the diameter of the field stop, hence the reason for 2" eyepieces. When using 1.25" eyepieces you can screw the 2" filter into the 2"->1.25" adapter. Check first that the eyepiece barrel doesn't protrude too far.

Cheers
Steffen.
