with mini buttons do you mean menu buttons on the main bar ? because if you do these are basically the same buttons that are on the right side as well (you can't know what buttons the users have assigned where as one can choose them from the game menu). Addition to that the same icons are used in the start menu thingie.
if so here's the tags (list taken from my skin as they are a bit scattered in the original skindef. the filenames and paths are custom so disregard those) ^^

I can't help you much (because of the obvious reasons, Thanks to CM for still not launching F2P in EU) with the new ID's but I think those store related buttons (Accelerate deed button and the Get more space vault button) are called "Chargen_*" so look em up with your picture browser and see if you see something that would match.
The uppermost element for the vaults are:
