In terms of naming, no. Comic Life 3 has all the Deluxe extras included in it - the extra fonts, styles and templates. Having the 2 versions of the original Comic Life was a little confusing so we decided to have just the one version and let it have all the Deluxe extra goodies that made Deluxe what it was. So for those people that had Comic Life Deluxe 1.0 - you will not be missing any of the Deluxe extras.
You can access the Deluxe styles using the "Blank (with Styles)" template from the Template Chooser.
