Hi Jed,
I used to have a similar kit, but it was pretty crappy. Once you have seen proper glass you will never go back.
For widefield you can get a GSO 2inch (or 1.25 if you dont have a 2inch focuser). I got a 20mm 2 inch...and it blows the view from my 24mm meade 1.25inch...its really good value for money.

And then spend a bit more money on your high power piece. Having 2 or 3 good pieces will all you need, especially if you have a barlow, then its like having 4 good eyepieces.
