I would recommend something in the 40-80mm range for a low power eyepiece (it would be 2", of course).
If 1.25", stick with 35mm and shorter for low power, since otherwise the apparent field will be excessively narrow.
On the high end, 15mm to as short as 7.5mm will occasionally be useful, though you'll find eyepieces with exit pupils that small will exacerbate the problem with floaters in the eye, especially if used on the Moon at those powers.
I would bet a good 12mm would get a lot of use.
The 80mm aperture does constrain the scope in terms of magnification.
It's reasonable to think of 150x as about the maximum for this scope. Fortunately, that's high enough to see details on Jupiter and Saturn, though Mars might appear a bit small except around opposition this May.
Details on Mercury, Uranus, and Neptune are the province of large scopes.
