Dso's seem to be an aperture game to get the best views. My main concern with going for only the 80mm triplet is how much more will I actually be able to see compared to my old 55m refractor? Does an extra 25mm aperture really make a big difference?

Also, what seems to be the general consensus on eyepieces and barlows? Are Televue the way to go?

You might see Uranus & Neptune as very small discs in an 80mm under ideal conditions, but don't expect too much detail! I have only viewed them with an 8" f/5 Newt with 2x barlow. Others will advise here.
Going from 55mm to 80mm is a ~ 45% increase in aperture, but ~ 2x increase in light-gathering.
Televue EPs are very good, but quite pricey. I have a few and consider them the best I have used. They appear periodically on IceTrades (like now!) for reasonable prices. As they are generally looked after, they are a good buy 2nd hand. The Naglers are the most popular.
