Been playing this TC a while now, I'm enjoying it. But I'm unsure of a few things...

Is the ring you start with a vital item? Would selling it screw me up later in the game?

Is there a full walkthrough available anywhere? I've looked but not come across anything beyond the tournament.

Is much of the music scripted?

There was an MSVCR71.DLL application extension in the download, what is this for? Can I delete it?

And unrelated to Arktwend, how would I go about removing unwanted creature additions from beastsofVvardenfell?

Thanks.
