Hide parts of marketpress store settings

Hi all

I'm trying to remove/hide certain parts of marketpress' store settings. Some of the settings just aren't relevant to my network , and some are, I just don't want them to see them.

Within a particular tab, I can hide certain fields or modules with css, so, my question is twofold:
1) Is there a better way than hiding with css? I know its not ideal in terms of semantics, but I'm more concerned about marketpress functionality.
2) How can I hide an entire tab but leave its settings intact?

In both cases, I'd rather not have to alter MP core file.

I've dug up a few threads about this topic, but none really addressed what I'm aiming to do, so if this has already been answered, I apologize.

Thank you!!
