With a pump, you can skip meals for a day if you like, though you
should not do this for basal testing. There is a HOWTO on the insulin
pumpers web site that describes in some detail how to go about basal
testing. The short version is: to break it into 3 or 4 managable
periods of the day starting preferably with nights. Duplicate the
profile "curve" for each period then adjust your basals accordingly.
Most people only need 3 -4 different rates. There is also a
simulation tool on the web site HOWTO page that will give you a good
idea of what to expect for a give change of basal rate.

That will go away as you become used to "normal" bg levels. Aim for a
little higher night time level, +20%

Read the HOWTO. If you have a copy of Pumping Insulin (you should),
read the chapter on basal rate testing.
