Pot with drainage chamber?

I have a pot made with clay/cement/etc i don't know (something hard) and it doesn't have a drainage hole. It does however have a flat black plastic at the bottom of the pot that has holes perhaps for draining?

Can anyone give me more information of this? I have 2 of these pots and I'm worried about drainage and wondering if I have to drill holes at the bottom or just let it be.

Here is a crappy picture to help:



This will be my first grow and I want to know if I have to go get a different pot, drill holes, etc.

Also, can I plant my germinated seeds inside a paper cup and transplant it to a permanent pot later? Does it have to be a plastic pot?

Thanks!
