I'll have the summer to test the set up and make sure it's working properly and that I can get good images when the time comes.
This is the most important advice...practice, practice, practice.
As East Wind Photography notes, the comet, even if it's spectacularly visible, it's going to be a relatively faint object in the sky. A solar filter will render absolutely everything black except for the Sun itself. It can be a lot of fun to play with...but only if you're photographing the Sun and nothing but the Sun.
A really good way to practice would be to shoot the slimmest crescent moon you can, either right after sunset or just before sunrise. When the comet arrives, the best photographic shots are going to be when it's near the crescent moon, and it'll be roughly as bright. If you can get a great shot of a crescent moon, the comet should be just as achievable.
