Perhaps you should do a little reading up.
I recommend "The backyard Astronomer's Guide" by Dickinson and Dyer.
It's the "Observer's Owner's Manual" and it would be wonderful if this book accompanied the purchase of all scopes for newbies.
Each of your questions could elicit a 50,000 word response, with chapters.
Nonetheless, I will try to lead you to a few sites where you can get some decent answers to your questions:
1) A short book that might be considered the owner's manual for the novice:

2) Eyepiece basics:
http://www.quadibloc.com/science/opt04.htm
3) How to evaluate eyepieces:
http://www.eyepiecesetc.com/Eyepiece...parameters.htm
4) Recommendations for how to choose them for a scope:
http://www.eyepiecesetc.com/1X_2X_3X...n-1x-2x-3x.htm
5) What filters are, what they do, and how to choose them:
Nebula filters:

and
http://www.prairieastronomyclub.org/...ommon-nebulae/
Color filters:
http://www.lumicon.com/pdf/3filterspec_prnt.pdf (go down the page until you get to color filters and what they do.
6) Contrast: what it is and how it's improved:

And if any of the concepts and ideas explained are a little too obtuse, you can always ask more questions. I bet your next set will be a little less generic and a lot more specific. It's a journey, and you're just starting on the trip.
