Yes to all questions.
Its up to you if you want a ROM or not. But if you root, and would like future updates, you would have to flash a ROM that incorporates the updates, such as the long awaited 2.0 or 2.1; the other alternative is to un-root to update. The only caveat to that is the exploit may be patched with the update.
After you root, take a nandroid backup in case you remove something important. You'll go back to the stage after rooting but prior to removing applications and such.
