For your steam id you can get this by...
Open up your css. Go into a server. Press ~ and your console will open. If it does not open press Esc. Then go to options. Then click keyboard. Then click advanced. Then press apply and ok. Then exit go back to server and open the console.
Type in status.
Open CSS > Get in server > Open Console > type status > find your name and it should say something like STEAM_ID:---------------
I can help you out with any further questions.
