Questions about making a Semi-Classic RP Server

[EQstarr]

I would like to start building a roleplaying server for EQ which would be focused more on trilogy content, but would have some elements of other expansions such as Luclin and PoP. Elements that would not take away from the classic feel of the game such as traveling by boats. I have a few questions to start off with:

1) Would it be better for me to start with the AX_Classic Database and integrate elements of future expansions that I want into it? Or is it better for me to work with the PEQ database, lock things out that I don't want or need, and change zones like Lavastorm back to the old version?

2) How can you change the name of the languages? I believe Live changed the Common Language to Human Language and only gave Humans a max skill in it for the RP server there.

3) Once I begin work on the server, will I be able to update the database when there are updates to either AX-Classic or PEQ without destroying any customizations that I've made?
