Default TDA2030A kit question

I am in the process of building a TDA2030 and came across something in the instructions that I don't understand.
"TDA2030A's cooler base and 3 pins are conductive, you need use silicotic film and insulation rubber ring to insulate IC and cooler"
I understand the film but what are the rubber rings and where do they go?

Thanks!

they go between the screw head and the TDA package, its only needed if the heatsink have conection with the ground (chassis or something else)

I think its easyer to use only silicone pads and single fastener without need to drill several holes and buy these nasty plastic spacers...

I have a few questions, and am hoping somebody can help me. I just bought this kit, and am wondering two things:

1. What do I do about a heatsink? One is not included. Any advice on what size to use, how to attach it, etc., would be welcomed.
2. Also, can somebody please tell me how to power this thing? I am a novice, just learning to solder, and have no idea how to get a power source to this unit, or what I should get.
3. If anyone has experience with this unit, can you tell me if I'm right to assume that there is no on/off switch? That the power is controlled by plugging and unplugging it? Thank you!

Please have a look at this page. This is a very exhaustive guide. It has a video too.
Construct a 30-watt amplifier low cost

It shows how to build a TDA2030 Amplifier with step by step guidance.
The circuit is in the PDF download. It also shows how to connect a power supply and tone controls etc.
All the very best.
