Hi Iron Dragon,
I've been running an Eberron campaign for (yikes) six years now and we recently switched to Pathfinder. To be honest, I didn't find anything that had to be radically altered to make the campaign setting work with pathfinder. Just the usual 3.5 to pathfinder stuff.
I've found the races and the artificer work work fine. The only thing I'd suggest was a house tweak we used with the artificer back when we used 3.5 rules. If your player is playing the artificer to be the magic-item-maker-guy then you need to address the time issue. There is no real way to make items while traveling unless you allow the lab in a bag trick using a portable hole.
That was the only drawback with the artificer.
Have fun with Eberron. We've enjoyed the heck out of it.
