I'm trying to play a guitar tab but it says the original recording is in the key of Abm. Does this mean I have tune my guitar down or use a capo to replicate the original recording?

Good question, I'm stuck on this too. Actually I believe that the harmony must be Abm, so if you'd name the pattern in that tab it would be an Abm scale or something (with improvisations)
no if it's in the key it just means the notes stem from A FLAT MINOR so to improve use those notes

I ran into some fingering issues. I can get it up to speed the way I've been fingering it, but I'm wondering if you guys have any better ideas, because it seems like there should be an easier way to finger this.

Don't worry there is Roc, there is
