Detailed q's about iTunes library xfer as it relates to a new iPad

Question

I just purchased a new iPad4, upgrading from a first generation iPad. I have a few questions about how I will transfer all of my apps, music, etc. to the newer iPad. And, I don't think it's as simple as restoring via iCloud. Or... maybe it is.
I'VE A FEW FACTORS TO CONSIDER:
1.) I've always had my first generation iPad synched up to the family Windows "Vaio," as opposed to my iMac. (Long story as to why. Had to do with bending to my family's needs at one point in time.)
2.) I wish to move--as I said--all of my apps and music FROM the FIRST generation iPad to my new iPad4
3.) BUT! NOW I wish to synch my new iPad4 to my iMac... and to drag along the iTunes library that exists on the Vaio.
Q: What workflow will I adopt?
1.) Should I synch up my new iPad4 to the Vaio, then... synch THAT to my iMac. (Will my iTunes library transfer over to the iMac? Something tells me it won't)
2.) Would iCloud help me at all?
3.) Would I start to add MORE stuff to be backed up on iCloud? (I'd just as well delete all the stuff that USED to be backed up on my First generation iPad.)
I hope this all makes sense. I woud appreciate any help.

Answer 1

I'll do this. And check back.
One more Q:
When I go to backup my new iPad to iCloud, won't it duplicate much needed storage space?
Should I wipe my old iPad clean, back it up to iCloud, to avoid duplication? (I'm gonna donate the "wiped" iPad.)
I hope this makes sense.
