Assuming that your battery ground cable (the fat one) is connected to the
engine block an additional ground strap from the starter bolt to the frame
will not help. If, however, the battery ground wire is connected to the
frame, it will help. Just be sure that you have at least one #8 or larger
ground wire from the engine to the frame or your choke cables and
accenerator cable will be the ground wires!
Having your alternator grounded to the frame and body is probably ok, but
would possibly be better if it were connected to the block. If the
mounting of the alternator to the engine gets corroded the charging
current will flow through the wire to the body/frame, then back through
the engine ground strap to the block. This gives you more connections in
the circuit where a voltage drop could occure. Run a wire from the
alternator case to the block just to be safer(er).
As for the ground strap extending the life of the starter, it could allow
the starter to get higher current (battery cable to the frame), which will
allow the starter to turn over faster and thus not have to grind as long
or as slowly as it would without the ground strap.
