Onkyo 606 questions?

[jruc03]

I currently have a samsung htib system and want to upgrade so that i can get the HD audio tracks when watching bluray through my PS3. I've researched the Onkyo 606 and I believe thats the receiver i wanna go with but i have a few questions.

1. I gotta use the old speakers my HTIB came with until i have the money to upgrade those as well, my question is how do i connect those speakers with the receiver since the Onkyo doesn't have the old style speaker wire connections.

2. The Onkyo doesn't seem to have a connection that i can use with my old subwoofer. My subwoofer isn't powered and it just has the speaker wire coming from the back that connects using the red and black leads. Will my subwoofer even work with the Onkyo?

3. Last question if I can get them all hooked up will the Onkyo reciever break or hurt my old speakers since they are just a HTIB set?
