I never got the email, other people said they haven't also.

Aalen chan posted the email information on larc LJ

LArc US Street Team also posted this:

"If we have not received confirmation of a fix in what appears to be a glitch in the system, we plan to upload the information from the email. By approximately 9:30am est"

As of now it looks like there isn't a password for presale, only the ticketmaster link.

I'm not sure about VIP or seating arrangements.

Just grabbed this image off ticketmaster site, shows the general seating areas. Of course, L'Arc show might not use all the sections but it does look like there is a lot of standing room in front of the stage though it might be convertible to seating, not sure.
