Im new to this, so im not 100% sure of how to should even look like.
Probably overkill, but in cases where you aren't sure, it's not a bad idea.
Also, for wifi capabilties, do i order a specific arduino board, or is it just an accessory i plug?
can i use the starters kit for my needs?
You need an Arduino and a WiFi shield. Which Arduino depends on how "beefy" you want your code to be. From what you described, an Uno should suffice.
