I would go with one of the following options:
Option 1:
32mm Tele Vue Plossl for 1.3deg field at 38x with 4mm exit pupil.
20mm Tele Vue Plossl for 0.82deg field at 60x with 2.5mm exit pupil.
2.5x Powermate for effective 12.8mm and 8mm with above eyepieces without altering eye relief, giving 94x and 150x.
The 32mm would be great for low power scanning and the 20mm for mid power scanning to better spot the smaller objects. The 12.8mm would be great for galaxies and globulars and the 8mm would be great for planets.
Option 2:
32mm Tele Vue Plossl
11 or 15mm Tele Vue Plossl (or both)
8mm Tele Vue Plossl
Note option 2 is cheaper initially but the smaller eyepieces have shorter eye relief and if you need glasses for viewing I would not recommend this option otherwise it is an excellent alternative. You could add a 2.5x Powermate later to get an effective 6mm with the 15mm Plossl but with much better eye relief than a 6mm woulkd normally give. This will give you 200x and about the maximum you would use your telescope on most nights. If you go with option 1 then you can add the 15mm Plossl later to get 6mm with your Powermate. If you go the 2.5x Powermate ask for the latest one which is threaded for 1.25" filters (early models were not).
The Tele Vue eyepieces do give nice bright and sharp images.
P.S. All calulations to 15cm f8 (1200mm f.l.).
