I've got a couple of friends in Sri Racha and I have been there several times. It's a small city of Chonburi province yet it is a very progressive one. Night life is so alive in the province so you would never experience any dull moment in there. They have a couple of pubs and disco bars located right at the heart of the city. Cool club is one of those.
When in Sri Racha, do not miss to visit Sichang Island which is only 45-minute travel from Sri Racha city. If my memory would set me right, the fare is only 45 Baht one way and then you could rent tuktuk for 200 Baht to have a tour around the island. You could also rent motorcycle and drive around the small settling.
I hope those info would help. It would be better if you would specify what kind of advices you are looking for like hotels/hostels, places to go, etc.
