The number of kinds won't count against your index quota. Here's a good article describing how the datastore works underneath the hood:
http://code.google.com/appengine/articles/storage_breakdown.html A single index exists for Entities by Kind. What you'll need to watch out for are the indexes you use on properties. Where I'm seeing red flags is the sheer number of types of entities you are storing. There's a danger here of overengineering and creating a new class simply to store additional information about very similar objects, and you may want to look into storing this additional metadata as a field instead. Having 100+ entities is going to be very unmanageable and could be extremely difficult to maintain.
