If you have good trinkets/normal gun, I'd upgrade those first. I took my 496 Taoren to 504 ASAP because the weapon damage is the biggest initial DPS boost. I then upgraded my relic of Xuen, and my H-Bottle.
Some items after that:
H-wrists off H-Stone Guard are essentially BiS if you can't buy the 509 wrists off the BMAH. That was next on my list.
If you have some H-bosses on farm in HoF, the cloak off Garalon and the neck off H-Blade Lord are BiS, I'd go for those. Obviously tier hands off H-Wind Lord (those are considered the "easy bosses" in H-HoF).
Otherwise, the H-Fetters off H-Gara'jal will be BiS until H-Shadowgrip, which is off H-Sha, so you could upgrade that.
After that it gets murky - I'd pool VP til I got a good piece from H-HoF/ToES rather than spend it off of something from H-MSV.
