Here is some info about the log.ini file which is used to set what you want to log or not:

I don't see a full example of the file there, but I think there is one somewhere around here.
As far as the errors you listed so far:
0x43ba is just an opcode that we don't need for EQEmu, so we just ignore it. No need to worry about that error.
Your "AccountName" error might be related to how you have your account setup and minilogin setup. I don't really know a ton about that.
The last error is probably related to the "AccountName" error, but again, I am not too certain.
Sounds to me like you might just have your minilogin setup incorrectly, but if so, you probably wouldn't be able to get to char select and definitely not in game.
SoF has no trouble displaying the new weapon models and icons as long as you are using a legal fresh installation of SoF directly from the CDs with no patching at all.
