Get your undertaker maxed then get your doctor upgraded.

even over getting purples and blues for my glads?

Purples/blues get their value around the elite/juggernaut ranks before that it is fairly easy to get a winning streak with greens if you intend on it lol

I refresh purples about every 10 levels so that would be 1(Although i give them greens at this level atm), 10, 20, 30 like that also you didn;t mention the option of purples/blues but only named vault, doctor, undertaker

Second level of undertaker is the best outof all of them followed by a fully upgraded doctor (Although i doubt you will be paying that much money for it so you might aswell ignore it xD)

About vault spaces: I take 1 space for every glad i own with a minimum of 3 spaces. 1 glad = 3 spaces, 5 glads = 5 spaces, just like that lol

Unless you plan on keeping your old equipment or keep something that is still to high level for you to wear 1 vault space would do just fine but having a few more is always more convenient

As you enter tournaments you might want to increase your vault in order to change weapons depending on your opponent.
