Insight into Step 2: There is no requirement that you host your reverse DNS with your authoritative DNS provider.  If you just want to set and forget your reverse DNS on some individual IP addresses, there's no particular need to host your reverse DNS at UltraDNS.  If however you'd like to be able manage your reverse DNS across a large range using the UltraDNS user portal, then it is convenient to delegate your reverse DNS to UltraDNS.
