A crowbar is a must have, relatively easy to use and not very heavy, and it's useful as a tool.
Short. Hair.
Don't be a pussy and wait for your mate who just got bitten to turn, kill 'im now!
Help other survivors if able to.
I'd head North.
Use single shot rifles or carbines, pistols (With a laser sight if available) for shorter range. No bloody automatic weapons, you're looking for accuracy, not filling up the air with bullets (This is for the Americans out there.)
Get your friends and family if they're able to be gotten, if you can't get to them, JOIN UP WITH A GROUP.
Use a bike.
Armor plz, leather would be most useful if you want to still be able to move.
