Hi Roy,
It's hard to tell if there's anything wrong here, unless you are getting complaints from other sources. The Steelhead says it's retransmitting about 0.2% of its packets, which can be considered normal in many environments. The TCP timeouts could be network-related, or server-related (e.g., overloaded server).
I would assume things are okay unless your users are reporting issues, or if some network reporting tool is complaining. Not trying to be a salesman here, but Riverbed Cascade would allow you to pinpoint a problem pretty quickly here if there was one.
