Oh yes! Thank you all so much. I felt kind of silly thinking that I should have been able to figure this out. Anyways, I hope it will help out anyone else going through the same thing.
Matthew, your first work flow fits my needs most appropriately as I have updated and kept components, extensions, etc. that I intend to keep using. Where I kept getting hung up was the database part in preparing to go live with the dev site. You answered it well with:
6. Update config.php (connect the new design to the original database) and make sure to double check all module settings, etc.
I just didn't understand it to be that simple.
Thank you all again! Now, I can finally get rolling with Dimensions and the RocketWerx special edition variants!
