I don't think you can actually go to the mayors desk until after your first day has passed. Isabelle keeps saying 'just relax today; moving is stressful' or something to that effect, and you likely also have to rack up the 100 Mayor points.
I got most of the tools already; I bought a fishing rod and shovel from Nooklings junction, and bought a net from Isabelle and she gave me a watering can. Still is a bit annoying putting up the stop sign the way they did.
I haven't gotten a call, but then again, the primary phone number for my GameStop Rewards account was our landline, which we long since deactivated. I updated it to my cell phone number, though, so maybe I'll get a call soon XD
I haven't seen if it's been posted anywhere else yet, but on the Official Website, Nintendo has posted the official Event Calendar for New Leaf: http://www.animal-crossing.com/newleaf/new-day/
A bunch of other features were added to the official website, too; the 'Play, Connect, and Share'...
