Opengts Database Repliclation to external server and make default spanish

I have new opengts server working Ok. Now we want to replicate the database real time to external server so we can get the data from mysql and ussed in another system that is very expecific for public security. I need sugestions in how to do this. 1. First time replicate all the data after that replicate only changes or only foward the fiels that they need. What would be the best? At the end we need to give customer ID and Login to get the data pull the data in real time. I think we need store procedure but you suggest the best option 2. Second the server all ready has spanish module and you can select it when you login. We want spanish the defaul lenguage for the customer so we need somebody to make it default for us so users do not have to select it is default. This job is very small so please if you bit tell me the number of days to complete
