Hi Mike,
There has been a heap of great info already however I think it would be best if you decide where your main interests are first, whether it be deep sky imaging or planetary.
Maybe it would be a good idea for you with your current setup to have a go at Planetary imaging. Your EQ5 should be able to handle it well as tracking accuracy is not overly important and processing planetary images will give you the skills to later confidently persue deep sky imaging. A Toucam will give you good results but I remember them being quite hard to find at a local dealer.
I think you will find planetary imaging a little less challenging than deep sky work with your current setup but by no means am I saying that it will be easy. Your enjoyment for both deep sky imaging and planetary work really depends on your image capture skills, your processing skills, your enjoyment for it and ability to ask questions.
You are on your way now...
