You're describing multiple problems in a single Email.  This is liable
to get complex.

1) It would be helpful to know if you installed i386 or amd64 FreeBSD,

2) With regards to the lock-up after "mount root", if you press NumLock
or CapsLock, do the keyboard LEDs turn on/off?

3) Many others have seen the hanging/lock-up after "mount root".  I
believe one found a workaround by setting ATA_STATIC_ID in their kernel
configuration.  I realise this is a problem when you can't get the
system up to a point of building a kernel; chicken-and-egg problem,

4) The Realtek NIC on that motherboard is probably too new to be
supported under RELENG_7.  Realtek has a history of releasing different
sub-revisions of the same NIC/PHY, and the internal changes are severe
enough to cause the NIC to not work correctly (under any OS) without
full driver support for that specific sub-revision.

All above said:

Can you please try one of the RELENG_7 ISO snapshots at the below site,
instead of the official 7.0-RELEASE ISO, and report back if that solves
either of your problems?  The below site contains ISOs built daily,
rather than monthly:
