Is it just me, or was that stupid?

Ok, so my technology-challenged mom may have made some major mistakes recently that I'm afraid have messed up all communications in and out of our house.

1. We got a new internet provider, switched to Broadband from qwest.

2. Purchased a "magic jack", a type of phone service that hooks into your computer and siftens phone service off your internet while you pay a much cheaper phone bill.

3. Shut off the phones.

ok, so the third one concerns me...her intention was to eliminate (or cheapen) the phone bill. By getting this "magic jack", she thought we no longer needed a phone service...but doesn't getting rid of our phone service kind of kill the internet?..

is there a way that we can still use this magic jack and have an internet, hence, a telephone line? Or was our phone service supposed to be provided by qwest, along with our internet?

I am so confused, part of me doesn't even understand what she did exactly. All I know is the internet's not working, and neither is the phone, not even if we plug it directly into a phone line.

Can someone explain to me how this all works? (especially if you have broadband high-speed internet from qwest?) Can she shut off the phone if we get internet from qwest, or is it all one deal?
