1) Hell yes! The Meridian's sound great, but Trifield will require a center channel.
2) I think the )A13's are only for the newest Meridian pre/[pro's
3) No, they do not.
4) The Meridian room correction is a PITA and only does the lower frequencies, up to 250 Hz I believe. I have had the 861v4 and v6 and despite numerous attempts never really got the room correction to work at all. I loved the sound of them so was never bothered by that though!
Hope that helps some, FWIW the older Meridian's can be a little difficult to set up. The computer software for their setup is great once you get used to it but there is a definite learning curve......
