Agree with Matt, an EQ mount even if not hooked up to a lappy, is a steep, steep learning curve, you will see more, learn more and work out if this hobby is for you using a moderate sized dob. 8" is sufficient to see hundreds of objects and will be much cheaper.
Star party is also a very good idea.
The photography learning curve is even steeper again, and very expen$$ive, so be really sure before venturing into it. I wouldn't touch that camera with a barge pole, if they were any good, the experts on this site would be using them instead of spending thousands on dedicated CCD and modded DSLRs!

Get one and you've probably spent a couple of hundred that would be better spent on quality eyepieces for a dob.
