You could jump from 5.0 directly to 5.5 and skip 5.1. I have without any issues. There are some configuration file change, which you may want to consider checking. I definitely recommend upgrading your development servers for an extensive testing. Some queries _may_ run slower or not work at all and you may have to rearrange how you join tables in your queries.
The upgrade from 5.5 to 5.6 should me smoother, though.
