Re: more terminology ques...
Cortland and Orvis should have some information on their website. You will just need to find the right link once you get on those. I found a website named troutlet.com that had some concise information on the correct fly lines with the right tippets, etc. Any local flyshop would also be happy to help you. Orvis also has a live chat room that you can talk to someone. Also Cabela's or Bass Pro or Gander Mountain personnel should be able to help you. Hope this helps!
"I fish because I love to; because I love the environs where trout are found; because trout do not lie or cheat and cannot be bought or bribed or impressed by power, but respond only to quietude and humility and endless patience...because only in the woods can I find solitude without lonliness..." Robert Traver 1964 (Judge John Voelker)
