I'm tired to be blind in MS SQL and Delphi 3

I'm only beginner in C/S programming.
Who can tell me how can I work with my MS SQL & Delphi 3 on new machine (another user and security context):
 a) what to install to this machine;
 b) what DLLs are required from BDE, SQL Linsk, MS SQL
     Client tools;
 c) what's about permissions (I add new user to my database grant all permissions to him, but my application
tells me that user name or password is not correct (login
failed) or table is not indexed);
 d) what's about problems with transactions on records with
     big size. (When I try to call MyTbl.Post in transaction
     I recieve an exception that network's possibly failed);
 e) where can I find documentation or books about
     Delphi 3 & MS SQL programming and tooltips;
 f) where can find out my fault when GPF occures in     Borland SQL Links DLL?

With best regards hansmtbank!
