How to control form and event rendering for a custom content type?

I'm prototyping numerous modules that provide custom content types. I've written a basic Event API module as I thought it would be quicker than trying to learn how to use the Event module programmatically. Now I'm second guessing myself and considering replacing my eventapi module with http://drupal.org/project/event and http://drupal.org/project/event.

I played around with these two modules and they provide the same basic functionality as my eventapi module. However, I see that I have no control over the rendering of the event. When my form is rendered the event is displayed before my content is rendered in hook_form function. Also, I render my content type using a custom template file but the event is automatically rendered my template file is rendered.

I may just be missing something important here but how do I either control how and when the event is rendered for my custom content type, or how do I disable it from being rendered so I can render it myself? And similarily, how do I control the rendering of the form? I know about the hooks for altering the forms; is this the best way? I want to display the event form near the bottom of the page and I would also like to control (per content type that has an event) whether the user can enter an end date and/or times.

Thanks for reading this!
