You "should" be able to, though I have no experience with them.  Look at
the top of the dark slide.  Are there five dots or bumps there?  If so,
then the dark slides are IR-proof, and the holders will probably work
just fine.

This won't work because of the different development techniques for
these film types.  Also your meter will probably be different and your
lens will certainly be different.  Anyway, you're not going to shoot an
$8 roll of film, develop and print it, and get back out in the same
light to reshoot.  Best is to assume that the first box (yes, I know how
expensive it is) will be used to test the film.  

Shoot a scene with three sheets at the EI you've come comfortable with
(for me, it's generally about EI250).  Develop the first and print it. 
Certainly, there will be problems.  Adjust your development of the
second sheet and try again.  Chances are that the third sheet will get
you very close to what you want.  Was the exposure correct?  Look back
at your notes (ALWAYS TAKE NOTES) and adjust the film speed - shoot two
sheets - develop and print individually.

Soon, you'll be confident enough to shoot one sheet per scene.  Take
time of year, time of day, light conditions, weather, and anything else
you might think relevant into account and compare against your earlier
notes.  It'll become second nature after a while.

For tube processing shot at EI250, you might want to look at Rodinal
1+50 70F 9 minutes as a starting point.

Good luck -
