Since I have multiple characters that might need these level 45 quest items (& I like to know what the overall demand is for them), I compiled the following matrix of collectible items for each class's level 45 quests. I did not include the items for the first stage of the quest lines, since those are not collectible or transferable.
Please reply with any corrections...

Although most of this I compiled from my notes and scouring the class forums, Fizen's post http://forums.lotro.com/showthread.php?t=62380 really helped me fill in some blanks. Thank you.
