Re: cylinders, if leakdown was good prior to teardown (sorry if I missed this detail in the thread), no reason to not just reuse the rings and reassemble. If you are re-ringing, many will say to hone the cylinders, not to change them dimensionally but rather to introduce some texture to encourage new rings to seat. A shop experienced in Porsche machining (or just familiar with nikasil cylinders) will know what to do.

Re: checking the oil pump, it’s not hard to check them if you know what to look for. Mostly looking for scoring or pitting on the gears and the pump bores. Look up Glenn Yee, and Supertec or other Porsche shops can do this.
