Newbie needing information

I want to add the Asterisk PBX to my house. I need some information on what hardware I need for my Linux server.

Scenario #1
If I have 2-4 PSTN analog lines I will need a Wildcard TDM400P, right?

Scenario #2
Now, if I have 1 PSTN analog line I can use a voice telephony-modem of some sort? Of course the Asterisk software too…

Scenario #3
Now, another option is using Broadvoice’s BYOD SIP service. With this setup, all I need is a ethernet card and a broadband connection, correct? Of course the Asterisk software too…

Thanks to all for any information…
