I usually copy the GENERIC config and edit the copy. That way, I always
have a GENERIC config to refer/revert to, should the need arise.

You don't need to specify KERNCONF if you are using GENERIC. If you make
a copy and build from it, you can set KERNCONF in /etc/make.conf

For production use, go with RELEASE. It is very stable, with the only changes
being seciruty or other critical updates. STABLE, on the other hand, is a
somewhat more conservative development branch than CURRENT, so is prone to
change more than you might expect from day to day. However, it is very rare
that anything is actually broken.

This is determined by settings in your csup config file. This could be in
/usr/share/examples/cvsup/standard-supfile, but I make a copy and put it
in /etc/csup.system. Then set these variables in /etc/make.conf:

SUP_UPDATE= YES
SUPFILE= /etc/csup.system
SUPHOST= cvsup.<countrycode>.freebsd.org  # Pick a cvsup host near to you
SUP= /usr/bin/csup

(These allow you to cd /usr/src && make update)

Now check /etc/csup.system. Look for RELENG_7:

*default tag=RELENG_7  # This will get you STABLE. The tag won't change 
                       # during the lifetime of the 7 branch.

or

*default tag=RELENG_7_0 # This is for 7.0 RELEASE. When 7.1 RELEASE is
                        # announced, change it to RELENG_7_1 to keep up.
