Oh, I'd be sad to see you go, but you should have asked first!
There are several ways to get great deals on content. For example, this deal offers $20 worth of tp, three areas starting at ~35, and one expansion for $20: http://www.gamestop.com/pc/games/the-lord-of-the-rings-online-mithril-edition/97978
This package is currently not a good deal, but is regularly on sale for $5, which includes 500 tp and one revamped quest pack: http://store.steampowered.com/app/213179/?snr=1_5_9__405
That, along with a quad pack (expansion set) on steam or the lotro store, when on sale, will easily take you up to max level.
It may be too late now, but there are options outside buying packs one at a time in the store at least.
