I wondered if there is anyone out there who is willing to share the basics and point out, what they probably see as, the obvious to a very muddled beginner? My questions are:
1, I've seen all the online genealogy websites but which one would people recommend? (and why?) I've downloaded the 'my heritage family tree' program from myheritage.com and have put a fair bit of info on that (can info be exported from program to program or would I have to input manually if I swapped programs?). My wife has a fair bit of info from her side, Sir this, Sir that, baronet the other! - mine is pretty blank!
2, Does anyone have a list of information sources and be able to tell me what they offer? eg. birth certificates offer parents names etc etc. marriage certs? death certs? military records? What can be found online, what needs to be ordered?
3, What information do I need in order to 'work backwards', eg. I have grandparents names and DOB, how do I find G-Grandparents info? I've ordered birth certificate and Marriage certificate but I'm not sure what that gives me and how to work backwards from then? (I was hoping it would become clear when they arrived?).
Please...treat me like a fool, step by step instructions...this really does confuse me!

Thanks in advance, I know it's all confusing right now but hopefully it'll all get clearer/easier as it goes on besides I think this is an important thing to do for my children to have and to add to with future generations.
oh another less important question but are there places where trees can be written out on nice paper with good Calligraphy so they can be displayed in a large frame?
Cheers
