Digital Fire Pro and Contact Form

I have some working forms created from Contact Form Solution Pack and I would like to add some file upload fields to these forms. In particular I need the following features:
- uploaded files to be stored on the server
- uploaded image files to be resized
- progress bar to show upload progress
- data input via the form, other than uploaded files, to be included in an email (as per contact form solution pack)
- uploaded files to be easily identifiable with the email sent by the same form.

Prima facie it looks as if Digital Fire Pro can do all of this but from a quick look at the forums it seems this may not be quite so easy in practice.

Can anyone advise on their practical experience of combining Digital Fire and Contact Form?

Many thanks
