Having played around with the scope and eyepiece specs I think you already have two of the most useful focal lengths, they just aren't especially good.
Initially I selected the following as being of interest:
Then removed some to leave a 'minimum' set of three:
The 32mm
Panaview eyepiece has a 2" barrel and a wide 70-degree field-of-view. It will offer much nicer views than the 32mm
Plossl eyepiece so is worth the extra. Besides, it would be a shame not to take advantage of your focusers ability to accept 2" eyepieces.
Magnifications are:
10mm - 125x
17mm - 73.5x
26mm - 48x
32mm - 39x
I am assuming you won't be using a barlow.
