+1 to everything Paul said
If you go the HEQ5 path and use your camera for imaging to start with, you have the advantage of being able to focus on familiarising yourself with the mount and become comfortable using it without having to figure out the setup of a telescope as well.
This will also give you more time to consider which telescope will be best for your needs and goals. Then, once you're ready to get your telescope, you can focus more on that and less time setting up the mount.
I think the most important thing is to keep doing what you're doing - keep researching and seeking advice, and take as much time as you need.
I will send you some info and links to useful websites etc. via PM which I found to be very helpful when first starting out.
