Regarding WoW, Human is far and away the most popular, (something like 1/5) followed by Blood Elves. Undead is somewhere in the middle of the pack, with Troll and Gnome at the bottom.
For GW2 the polling right now has Humans at the top, followed by Charr. Sylvari and Norn are in the middle, but quite a bit behind those top two. I'm thinking the Norn will remain relatively low, while we have to wait on the look of the redesign to determine how popular the Sylvari will be. Asura are absolutely dead last, make one of those if you want to be unique... Unless the Asura week has some surprises to make them look absoultely incredible.
Personally, I'm a huge altoholic so I'll have at least one of each race. Most likely picking the race based on what class I'd like to be associated with it most. Definitely will have one of each class like in GW1. Will be picking depending on most to least interesting, but I'll have 'em all.
It's 30 for all the gear, this page helped me out tremendously when I was grinding out points:
Hall of Monuments Rewards. Don't want to miss out on the Stygian Reaver (28) and Fire God's Vambraces/Black Widow pet (30)!
