I mean - will playing a gnome warrior mean that, more or less, I'll be sitting in the middling ranks of pvp, losing out to 'more ideal' race-class combinations?
No, but Titan's Grip is more of a PVE thing. PVP go Arms (normally) or Prot IMO before Fury.
Seriously, racials are fairly even - IMO Gnomes are at the bottom of the stack and Humans are at the top, but it's not completely imbalanced like it was in Vanilla (Undead or GTFO).
Top things that affect winning in PVP (from most to least important)
Skill --> Spec/Gear/Professions/Teammates ---------------------------------------> Racials

Also - just how much does race matter when it comes to pve? Are things more or less the same for everyone, at some point in time - or does the gap become bigger at higher levels/better items/etc?
Race hardly matters at all in PVE. Again, Humans IMO have the best Alliance racials (Expertise and a free incapacitate break), but it's not a HUGE difference (again -- again, back in Vanilla, Priests for serious guilds pretty much had to be Dwarves -- luckily Blizzard did away with this philosophy).
Professions, gear, and talents again are the big things that will affect you performance in PVE.
For the most part, the differences between races in WoW are cosmetic. Your gnome warrior would have the same offensive and defensive stats as his counterparts. Also, gnomes look cool when they hit Heroic Strike. True story.
