It depends on what kind of cake you are making. If you are making chocolate, use chocolate. If you are making Vanilla, use vanilla. If you are making strawberry, use pink vanilla etc.
candy
For making cake pops you will need box cake mix of your choice, baked and cooled, some creamy frosting, white candy melts, lollipop sticks, and candy colours and decorations.
any baking store
I'm pretty sure you can use any candy.
Push pops can either be ice cream or hard candy. Ice cream is a solid a cold tempertaures, but a liquid at room temperature (it is mostly milk poroducts, liquid color and flavoring, and sugar). As it warms up, it will melt. Candy push pops are mostly sugar, with added coloring and flavors. Often the sugar is corn syrup or other liquid sugars. These, along with regular sugar, have a low melting point. When it get warm, the sugar will begin to turn first into a sticky gel and then to a liquid.
Yes, Walmart sells pink candy ring pops
You must either have a specialty cake pop pan in which to bake the pops, or you can bake a cake and crumble it up and mix it with frosting and form the mixture in to balls.

cake on a stick, cake balls? there is actually no other name for them
No. Angie Dudley better known as Bakerella re-created the cake ball (which by the way existed as far back as the 50's when everyone's grandma had a cake ball recipe they broke out for the holidays), however, Bakerella in 2011 took the cake ball one step further, stuck it on a stick, dipped it in colored candy melts then started shaping them into unique shapes and characters therefore, creating the craze of cake pops.
Ice melts at a standard rate proportional to itself, so if all ice pops are the same size they will melt at the same rate. However if some brands have wider ice pops than others, they will melt slower.
I'm pretty sure there are bakeries out there that carry cake pops and there may even be a select few completely dedicated to cake pops. However, cake pops are mostly a custom order item from small businesses aka. cake poppers online. Chances are if you go a search online for cake pops in your area, you will find someone. Etsy.com features a variety of cake pop stores. If you can't find someone in your local area, many cake poppers ship their goodies too.
