I found fishing relatively quick to GM - set up a macro to fish in one spot but 3 different locations (as far upstream as I could cast, as far downstream ditto and right in front of me). Repeat macro until all area empty. Move to another part of town. Repeat.
Did this in about 4 different blocks from 60 to GM in a couple of hours or so while I was working on something else with a different character.
Just my 2p.
EDIT: actually, looking again more carefully at the list, I'd say you've got it about right in the list. I'll leave my method there just in case it helps somebody. Nice list though, thanks.
