This seems like a lot of work for 3 fingers, I don't think I could handle it.
If I might make a suggestion, try playing a few games as an item/skill heavy hero so you can see if your fingers are really fast enough to keep up with the kind of speed you'll want to achieve one day:
TA: Phase, Bottle, Blink, BKB
Nightstalker: Treads, Bottle, Urn of Shadows, Armlet, BKB
Sven: Phase/Arcane, Blink, Mask of Madness, BKB
Storm: Bottle, Treads, Orchid, BKB, Sheep
WR: Phase, Force Staff, Blink, Eul's, Scythe
