If you want to play gba games on a ttds then you need a gba emulator compatible for the ttds but i don't think there is one.

You can get them off the internet, just search buy ttds. Also it depends where you live but there might be some shops around that sell them
go to amazon.com
Yes, TTDS / R4DS are illegal, but ONLY if you use them for "ROM"s. You can apparently use them for other kinds of media, like music.
No they can not go into dsi XL or dsi. There is a possibility that the system will break. But there is a dsi or dsi XL TTDS like chips.
yes it will work with any ttds any game that contains Pokemon except the game boy versions of Pokemon will not work
To load action replay cheat codes onto your ttds card, you will need to download a program called Cheat code editor (use youtube for help with that), find a youtube video which has the tutorial, and it will simply guide you through the steps for loading the cheats... I'm not sure if any of that was very helpful, it's just that's how I done it, but I can't remember all the steps to it, sorry!
Nope, not if u get the stupid update in DSi shop
