You can go directly into a BSN program if you are accepted. The 3 Fs might pose a minor problem in that they probably placed you into an "academic probation" type status at that school. Should be able to explain that or have the probation lifted. The CNA may or may not help, not always necessary for admission. I agree with the previous poster, however, must caution you that accelerated BSN programs are known to be difficult, and there are people who have to transfer to traditional BSN programs because of the fast pace.
