Sage,
There are two considerations when mixing ospf network types:
(1) hello/dead intervals -- sounds like you already know how to adjust those
to match
(2) Use or non-use of DR/BDR
Non-broadcast and broadcast elect DR/BDR, but have different hello/dead
intervals.
Point-to-point and multipoint do not elect DR/BDR, and also have different
hello/dead intervals. Multipoint may require neighbor statements over NBMA
so it knows which router to form an adjacency with.
Here is a good link to start with:
