Editing Cart Text and/or redirects

Alright, so I’ve got Membership and Affiliates up and running. When a user goes to the /register/ page they are presented with two options –either a regular paid membership or an affiliate. When an Affiliate account is created, the user is simply directed to the regular paid membership cart with some not-so-obvious text at the top saying they are now affiliates.

I would like to either…

A. Have an Affiliate signup lead directly to the page containing the [affiliatelogincheck] and [affiliateuserdetails] tags.

B. Edit the text at the top of the cart with explanatory text describing what the next step is with a link to the /affiliates/ page.

What is the simplest way to do either of these?
