Potential Vita owner questions

Hello everyone!

In a few days, I will be a proud owner of a Vita (especially now since the GameStop current sale) and I have a few questions:

1. Besides the color, are the GameStop Blue and the Borderlands 2 Vita the same model? Are their pros and cons on getting one over the other?

2. On the subject of Borderlands 2, how is the vita port? I've seen reviews about it being trash on the major sites (IGN, Destructoid, Kotaku, etc.), but actual owners have said they love the game on Vita.

3. Is 32 GB or 64 GB a good starting point on a memory card? I'm a digital gamer, but I do plan on having some larger games (Does the Vita even have "large" games?) being physical copies.

4. Any other recommendations for me? On my list now I have Ragnarok Odessey ACE, Soul Sacrifice Delta, Freedom Wars, LittleBigPlanet VITA (Marvel Edition), and Terraria. Also I have another list of games that I have from Crossbuy, which include: Don't Starve Giant Edition, Abe's Odyssey, Sound Shape Ultimate, Skullgirls (when it releases), and more. As far as my tastes go, I like dang near anything if it has awesome replay value' however RPGS and platformers are my go to genres.

Thanks so much guys!

Edit: You guys are awesome! So I'm going to go with the blue slim vita! Also the games I've chosen to start out with are: LBP Vita, Toukiden: Kiwami, and Soul Sacrifice Delta and when I get payed next week I'm going to pick up P4G and a few more indies. And I think I'm going to go with a 32 GB card since I have alot of games from PS+ sales and IGC that are for Vita and since 64 isn't in my budget yet lol.

I'm going to get my Vita sometime before next Wednesday and I'm really excited!!

Thanks again for all your help guys/gals!!
