Hi Jason and welcome. We all have to start somewhere and this is a great place to ask lots of questions. There are plenty of us here that have to make do with tight budgets, but still come up with reasonable results. I'll start with the first one yes you can easily fit a RA drive to your EQ1 mount and use it to take wide field long exposures with a DSLR. There are plenty of of deep space objects large enough to capture with a telephoto lens with a bit of tracking. This one is cheap and simply attaches in place of the RA slow motion control.

There are various adapters available to fit cameras to mounts. The only problem with astrophotography is that the more you spend on equipment the easier it gets.
