Unless of course the warrior(cheap wow gold) is not the main. we personally leveled our warrior to 70 as fury and had hardly any troubles at all give or take a few minor tweaks with the build. They can raid heal if needed through the use of Flash of Light and Holy Shocks, but you wouldn't want to assign a paladin to raid healing unless no other healing class besides paladins are in your group.

As soon as we hit 70 we went straight to prot. Basically, with the three specs from say 20-70, out of my own personal wow gold experience we would reccomend DW fury, however with all the changes to the talent trees now we can not say for sure how it would go, but if you feel like killing a few other players on your way to the top perhaps try a arms(buy wow gold) or fury build to get Mortal Strike as well as a few nice fury talents.

At the end of the day you can build your spec however you want it, believe me by the time you start raids you will know alot about warriors and what talents go together well and which get you dead. As an added note to you both we have leveled 70-79 as prot and have no problems with elite quests or any of the PvE side of things about wow gold, although we recently changed over to DW Fury again to check out titans grip.
