Joking aside, what you are proposing is probably overkill for the area and a bit more riding time and conditioning will make your 34x28 seem plenty deep. As a short term stop-gap the 12x30 Tiagra cassette shelbyfv recommended is the cheapest solution.

I do get annoyed at the posters who say "HTFU" when anyone mentions problems with hills but, in this case, the hills are quite modest and you will soon find them manageable unless you have a significant physical impairment.
