Surreal,

1. Either should be easy to move around. It's when you start getting into 12" aperture and above, that it can become tricky -- especially transport;
2. What you do is attach a T-ring on to your camera (these can be had for around $40) and a camera adapter barrel, which then slides into the focuser. This is called prime focus imaging. The other way of doing things is attaching a camera (with lens) on top of your telescope whilst it's on the mount. This is a piggyback configuration;
3. You should be able to see some detail, but, for maximum impact, you will need to travel out to a dark site. Check out the star parties forum to see if there's a society nearby you that you can attend. They'd love to have you along;
4. No such thing as a silly question -- just silly people! Just kidding!
A moon filter is a neutral density filter. The purpose of it is to tone down the bright eye attack that the Moon is through an eyepiece. It also helps to add contrast and allows you to see finer detail.
I hope this helps.
Enjoy your stay.
