Some questions:
*With my Cake Maker on the prices page, if I added lots of options, different colours, etc. (I'd also need a different interface or it would be far too long) would it be best to have a static image for each combination, or is there some way to dynamically build an image for each combo.

*How do I do mobile stuff?

*Is it safe to put email server username and passwords in a PHP file for the contact page?

*What other questions was I going to ask?

Just a thing or two I noticed:

The Tier 1 option on your cake maker has a borked link to the image. But you probably know that already.

Also, this:
 
Should have a comma in it after 'standard'.

I quite like dusky pink. :)
 

Yeah, I have noticed that bug. I've made a quick fix which sort of works. Only works properly the first time but at least it's not showing a missing image now.

I'd quite like to reword all the text at some point. Dusty pink is better than a dusty cake.
