This seems doable.
For the first weekend, and getting settled, I would skip anything that has to do with parts, sampling, or the arranger.
Throw some samples in a folder, load it up on the OT, start making patterns, explore P-locks, FX etc.
Hook up your synths, make the appropriate midi settings, and start sequencing.
Dont overthink it, and dont get married to any ideas, you'll have a completely different idea of how to use the OT in a month. A few moths later, you'll be on another completely different way of doing things.
