How doe Jitter and round trip time affect local time clock time acccuracy?
They don't *affect* the accuracy, they measure it!
When looking at the jitter, what values would tell me that the phase
noise would make the local clock in accurate?
Are there any "Rules of thumb" to go by when looking at jitter and delay
to determine local clock accuracy

How close do you need the time to be? Many people live most of their
lives with clocks that may well be off by a minute or two.
Other people need numerous clocks to agree with each other +/- a few
seconds, milliseconds, or microseconds and don't care that the time is
not correct as long as all the clocks involved agree within the
specified tolerance.
Still others need to know the time +/- a few microseconds or +/- a few
nanoseconds.
Specify your needs. If you can't figure out how to meet your needs,
post a description of your requirements and somebody might be able to
give you a clue or two or three.
