If you really want to play around with the data, then I warmly recommend
moving to a UNIX (or Linux) platform, and using for instance "nawk" and
"perl" scripts. It's not that hard to extract the sequence and other
relevant features once you get familiar with how genbank files are
structured (I suggest you have a look at the release notes which explain
feature keys etc:

IF, however, you don't really want to learn to program (I can't blame
you), then you may find that the GCG package can help you some of the
way (it contains tools for converting between different sequence
formats, and for doing various statistics, e.g.,
nucleotide/dinucleotide/trinucleotide composition, frequently occurring
"words", etc.). 

Good luck with your project!
