Hello and welcome on this site. I think you will find most of the answers on this site, but ofcourse I will try to help where possible.
FotR block is indeed the first 3 sets, and they are all printed in foil. Hard to get though, wildthinggames -a shop on Ebay- sells the most foil sets I believe but it is expensive. Other stores will have Fellowship cards, but it became more rare. So if you are to find a boosterbox -maybe at
www.wholesalegaming.com- the price will be like 40-50 usd. But I haven't checked in quite some time, so unfindable could also be an option.
The draftpack isn't that interesting. They contain a lot of commons and uncs, interesting only when playing a draft tournement or when you are really low on cards. Price would be like 2 usd. And I also believe they contain 1 random rare.
Each expansion has 2 starters. Fellowship has a Gandalf and an Aragorn starter, Mines of Moria has a Gandalf and a Gimli starter and RotEL has a Legolas and a Boromir starter. The exact content of the De Luxe starter can be found on wholesalegaming.com.
Two Towers is still an interesting expansion, with new options, new fellowships and luckily they go out cheap, due to the massive production, sadly they reduced printing after Bloodlines.
Cardlists are to be found on this site. At the top of the site you can find every set, except the foil versions, but that way there is something left to dream about. I hope I have given you something to work with, and please, just take time to roam around and find everything you need.....
