Here's the answer to all your questions! First get this book on CD: "A GUIDE TO ASTROPHOTOGRAPHY WITH DIGITAL SLR CAMERAS", here www.astropix.com This will be the best $30 you ever spent and the book will shortly become your bible. It will also tell you what equipment to buy, were to buy it and how much to pay for it. Also will cover how to use it and which software to use (much of the software is free. To answer your question about the telescope and mount...
A Celestron or Orion 80mm ED on a Celestron Advanced GT will cost you about $1,000 new, or far less used.

The ED80 scopes are great for astro imaging, that is good advice. I have owned the Orion ED80 and both Celestron C80ED and C80EDF Onyx versions either would work, but I'm more partial towards Skywatcher versions, and there is a great package deal on the SW Pro ED 80 with case, diagonal, rings, finder, etc right now I would investigate.
Guiding with the C6 may work, but that OTA does not have holes for top rail guide scope mounts, and you might have to investigate a side by side set up or a set of rings for the C6.
Having owned the CG5, and Atlas EQG, and I opted to go with a CGEM as my EQ mount like many others, and am very happy with the mount so far. Only the Celestron EQ mounts have the All Star Polar Alignment routine, and IMHO attaining an adequate polar alignment for astro imaging can't get any easier than with that routine. I'm sure some would say the CG5 would be adequate for the needs you have described and it might well be, but if it were me I would spring for the extra $$$ to get the CGEM as you have so much more flexibility for growth. Like Lance stated above you might want to get a C11 one day, and that OTA will be comfortable on a CGEM, but is just too much for a CG5 for any thoughts of imaging...
Of course you can keep your C6 from the Nexstar set up and use in on your new EQ mount and, I love my little C6 and use it on my CGEM often as it is a great grab and go OTA.
Hope this helps!

I recently was going through the same search you are in now, and ordered me a CGEM. You'll hear a lot of 'new and unproven' statements regarding the CGEM, but you'll also hear it is the 'new and improved' EQ-6. I think it is the best bang for the buck!!
As far as guidescopes, I am using the miniBorg 50 with a Q-Guider (SSAG) for my Megrez and couldn't be happier! Weighing in @ under 2 pounds with rings is a blessing.
