I know this sounds weird, but i'm looking for a device that will allow voip phones to connect to analog lines. is this such a device?

An FXO Gateway will allow you to connect to standard copper phone lines, and connect them to a network - and thus voip phones. It will be basic single line operation, unless you utilize a voip type phone system. Hope this helps.

If i wanted to simply convert a few pot lines to sip endpoints without a voip service, would this allow me to do so?

Yes. no internet access or VOIP service is required. You can connect this to up to 4 analog POTS lines and have VOIP service on the other end. One caveat is , I was not able to get my VOIP phones to communicate with this grandstream box directly. I think it should work but it was not getting through the authentication. But I was able to get Asterisk to communicate with it , and my phones with Asterisk.

We have 3 analog landlines. We want to turn them to voip and use ip phones without any recurring payments. Is this the right product?

Yes this will do what you want. We use this with FreePBX to accomplish what you described. The configuration will take a little work to get right. There are some guides online.

if today i bought, when the delivery date, I need urgent

I can send it tomorrow by expedite service if you pick this service
