Personally I'd get a new saddle first as an uncomfortable saddle is miserable and can even cause damage to those soft girly parts if it's very bad. While it's important to get some good pedals you can still ride if they're not perfect. Could you beg, borrow or steal a pair of regular flatties off someone for a few weeks to tide you over.

Just my 2p worth.
