In the OS X GUI, different wordings are used to signify the same thing.
As another example, the status bar enumerates the amount of items as "Torrents", e.g. "4 Torrents", but once more refers to the same thing.
"Transfer" seems the best choice here. It's universal (works for seeding as well) and not too technical or BitTorrent?-specific. The term "Torrent" as an item should refer to the torrent *file*, as in "Save a Torrent Copy As…" (cf. File menu), which is correct. Using it to refer to the transfers seems weird.
The inconsistency in Reveal and Removed Downloaded is that adding files for remove makes it more clear, but for reveal is kinda obvious.
