Hi there Prometheus.
You can't go wrong with the GS880, it's a good scope with good optics at a good price.
f/5 (fast) scopes though, are more taxing on eyepiece design and collimation. Collimation errors will show up more readily, and stars won't be sharp to the edge in cheaper budget eyepieces.
So the first step, is ensure that when you get your scope, you get some tools to help you collimate, and do lots of reading, and if possible, get along to some local asto clubs or observing groups (where's bomaderry?) to get some experienced guys to help you out. You need to know how to collimate if you own a newtonian.
For eyepieces, it depends on your budget. You said you'd prefer fewer good quality eyepieces, so that's a good starting point. Good quality may mean a wide FOV, or it may mean stars pinpoint to the edge. You can get either, or both, depending on how much you want to spend.
You can get quite a good widefield in the GSO SV 30mm, it's about 65deg FOV but stars won't be pinpoint all the way out. It will barlow well though, and become a very nice 15mm SV. And, it's only $70-$90. The Andrews 30mm UW is another example, with a wider FOV (82deg), but again at f/5 the outer 1/3 stars won't be pinpoint.
You can get good quality planetary/lunar eyepieces such as orthoscopics, that don't have a wide FOV, but stars are sharp to the edge and give good contrast on your selected target. They're also quite reasonably priced. Good quality plossls (such as televue or celestron ultima) could also be considered, they'll have a narrowish FOV (wider than the ortho), be sharp to the edge, and are suitable for a wide range of targets assuming you have enough variety in focal lengths for both open star fields and cluters, to galaxies and nebulas, to planetary/lunar.
When you're after a combination of both wide field and sharp to the edge, then you're looking at spending $200-$500 per eyepiece, for ranges such as Pentax XW, Televue Panoptic, Televue Radian, Televue Nagler.
You will need and want a barlow. A 2" barlow is definitely handy as they come with a 1.25" adapter and can be used on all of your eyepieces. A fairly good quality GSO 2x 2" is about $79. The next step up is the Celestron Ultima or Orion Shorty Plus, and then Televue 2x Barlow, and the premium is the Televue Powermate.
The barlow will double your eyepiece kit, so as Rob has said, select a range of focal lengths in eyepieces that won't be doubled up when you have a barlow. Eg: If you get a 17mm nagler and a 2x barlow, you don't need to buy a 9mm nagler.
You won't need a paracorr, cross it off the list.
Hope i've helped! Good luck and let us know what yuo decide! Keep asking questions if you're unsure!
