XF 1.5 Upgrading

[Archeon Khan]

When I upgrade to 1.5.7, will I loose all my templates, addons, members, and things along those lines?

No, provided that the thrid party add ons and styles are compatible with the newest version. With regard to the members, posts etc, the answer is no again. But it would be a good idea to make a backup of your database before hand.
