Understanding eyepieces

I'm hoping to purchase a 12" Dob but I need some help as I am confused to say the least on eyepieces and I was hoping if someone can direct me to a forum/web site which can explain what type of eyepieces are available. What does eye relief mean? Do I use 2" or 1.25" eyepieces? What is a Paraccorr and a Barlow and where would I use them? What does 35mm or 4.5mm mean? Then on top of that you have filters to contend with. I just find it difficult to comprehend the amount of information on eyepieces where all I want to do is just go out in my backyard and observe the night sky in the western suburbs of Sydney.Cheers
