Help on SQL*Net connection (HP-UX <-> NT)

I've to realize a connection between a PC with Windows NT and an application yet unknown,
and an HP 9000 with HP-UX, Oracle 7.2.3 and SQL*Net v2. I'm a newbie.
Do I need an ODBC to make the connection or the tools supplied by SQL*Net are sufficient? Do I need SQL*Net at both ends of the connection? Also I'm not sure if the installation (not made by me) is complete: listener.ora is present,
tnsnames.ora and initlst.ora aren't.
Then, I must send and retrieve big files (format .avi), so in the column of my table I will put the path to the file. What is the best way to do this automatically? A PL/SQL procedure?
Any help, also elementary, highly appreciated!
