In my opinion,yes it's worth it to change this gasket.
One thing I would recommend doing is before you
unbolt anything,take it to a self-serve car wash and
clean the heck out of the bottom of the engine,then
let it dry.Then drive a little and check out not only
the places you think it's leaking,but if the front and
rear seals are good,and if there is any leaking from
above the pan.If you change the pan gasket,now is
the easiest time to do the seals.And a Chiltons or
Haynes manual is handy to have if you don't yet.I've
used a torque wrench on even the pan bolts with
good results.Tendency to Gorrila torque here.And
more questions can be asked here if there is any
uncertanty about seal proceedures.Good wrenching!
