Token replacement pattern for triggered rules on node creation
This should be possible with the the above modules.

You do not need to get data from the form/form_state.

I'm assuming the data you want is from a cck field because you're sending the email when a new node is created.

Rules has the "Replacement patterns for saved content" field set for pattens.

In there there's going to be cck specific token replacements. You can use those cck tokens to get the data you want.

These replacement tokens will look like [node:field_name_of_your_field-formatted]

Also make sure you're using the "After saving new content" event.
