Is it easier to enter UC as an undergraduate or a graduate?

I'm almost done with my community college, but I'm currently still deciding between the following two:

1. First, I could go to a CSU. I could obtain my BS in another discipline by June 2009 and then attend UCLA/UCSD for my MSN - and be completely done with school by June 2011.

2. Or, I could try to transfer to UCLA now and get my BSN by June 2010 and end it there.

The thing is I'm not even sure I could get into UCLA as it is. I currently have a 3.06 GPA. I suppose I could raise it by June 2008, but I have to send in the application by December 2007. Does anyone know if I have a better chance at UCLA as an undergraduate student or as a graduate student? What are the requirements for going into UCLA as a graduate student anyway? What is the minimum GPA? Do we need to take any tests? I can't seem to find anything on its website.

(Sorry for rambling. I'm a little nervous now.)
