Remove certain teasers (storage upgrade, premium themes, etc)

I'm developing a site with 3 levels:
Free - ad supported, no money-making plugins
Basic - no ads, money-making plugins unlocked, storage bump
Premium - same as basic but priority email support

There are prompts for premium themes (which are all included even at the free level) and get a storage upgrade when at the basic level even though the premium level doesn't offer more. I'm doing generous packages and am going for simplicity in the plans, is there a way to get rid of the mention of storage upgrade for those on Basic and remove mention of premium themes throughout?
