Terry I know how you feel, good thing is, plumeria is a very forgiving plant....on positive note, if you can successfully root this, you will have 2 plants instead of one :whistling:
Cutting the leaves off will not harm it but will help it direct its energy to rooting. Bottom heat is important with the rooting process, I usually root them using a clay pot (around this time of the year) or cheap black pot and place the newly potted cuttings on paver bricks for bottom heat. If you put it outside in the sun, protect it from unwelcome rain. It is important to keep the cuttings more on the dry side, water once, then do not water again until new leaves start coming out. I wait until I have 4 true leaves.
Some use 100% perlite when rooting to help prevent root rot.
