1. When will a 64-bit compiler be available for Linux (ideally Red Hat Enterprise Linux x86_64)?
This is heavily being worked on: http://dsource.org/projects/dmd/log/trunk GDC and LDC basically support x64 but D2 support isn't mature.
2. Is ODBC supported? Is there a Phobos library or is it just accessible via C?
http://dsource.org/projects/ddbi http://dsource.org/projects/sdbo <- seems to be dead though
