If you want to be completely up to date buy this:
https://us.battle.net/shop/en/product/world-of-warcraft it includes 30 days play time and the basic game plus the Burning Crusade, Wrath of the Lich King, and Cataclysm expansions. Then you buy Mists of Pandaria which is the latest expansion:

Note that you don't need Mists of Pandaria right off the bat since it is for level 85+. The first link will last you until level 85, you only need MoP if you want to play a Monk character.
Playing WoW solo is fine, that's how I've mostly played the last couple years.
How often/what hours do you plan on playing? I'd do a Recruit-a-Friend with you if you want. Basically we would play and level together and we would get 300% exp while we are in a party.
