hi Matt,
The 8inch is a very good all rounder and many start with this, its by no means just a beginners scope, but can serve very well for some serious observation.
As others suggested, visit the MPAS for a viewing night, you'll get lots of ideas and know how.
this was my first scope as well, and one of the challenges I had, after viewing the planets and bright Globs, was locating objects. it can get frustrating sometimes viewing from a LP area, so have a look at making your own setting circle for the Azimuth. for the Alt, you can use a digital angle meter.
so that, along with stellarium on your laptop or phone, will help you find objects as you learn to navigate.
star hopping is how you'd normally locate objects and it can take some time but worth the exercise.
I'd suggest saving up for some premium eyepieces. the views through those for nebula from a dark site are stunning to say the least.
things to add to your list after you get it
the Az setting circle if the scope doesn't have it already, (you can add it
yourself by printing it out on A3, see Richard's thread here

An 8x50 right angled finder, your neck will thank you for it.

stellarium on a laptop or a planisphere or star chart
Eyepieces - have a read through the many threads here. the stock 25mm ones that come with it are pretty good, but worth keeping an eye out and saving up for a decent one. the GSO superview is a nice cheap addition for a wide FOV. As for binaries and clusters, I'm not sure what's good. seeing is an important factor for planets and binaries.
and shop around for the best price.
good luck
Alistair
