Some help for a noob

Actually, no. The target is stunned for 8 seconds provided you don't attack him. I've used that trick many times in both PvE and PvP. Rogue jumps me, Int Shout, bandage and kick his ass :)

Exactly--that was the trick that convinced me to put the auto-attack toggle back on my warrior's bar.

Since you only have a few seconds, having higher-than-normal bandages also helps out. When running an alt, I usually push every piece of cloth I pick up into leveling First Aid as high as possible just so that my bandages do more hp/time. Even my 45 druid has well over 250 First Aid. Nature's Grasp+Bandage ftw!

Of course, I have no experience from 44 - 60 with a Warrior so I can't be certain, but as long as you keep your weapon up to date, you won't have any problems.

Warriors are the most gear dependent class by Blizzard's own admission. The difference between bad weapon and good weapon can be quite significant in shaping your experience. Personally, I love upgrading so it was really enjoyable for me to see the gains from equipment while leveling (compared to my warlock who received more gains from the trainer)--but not everyone is like that :).
