You must have a 3.00 GPA to apply for BUCOP and must maintain a 3.00 for the duration of the program. The degrees are co-terminal; if you don't complete the requirements for the CAS degree, you can't graduate with the COM degree. If you have sufficient AP scores or you take college-level courses while in high school, you have a leg up on fulfilling the 144 required credits (compared to 128 for a single degree). I'm a current BUCOP junior and will graduate on time without overloading (I've taken two summer courses while at home in California so far).
As for which college you should apply to, that's up to you. I started in COM and then applied to CAS, which has worked out well for me because COM is smaller and more intimate. I guess I'd say apply for whichever major (Journalism or English) you feel you're a stronger applicant and have the better chance of being admitted into BU.
