Hasta La Motion!

Alright first of all im going to post all the questions i ask here for problems i may come across to save forum space, But heres my question right now

I import the track data from syntheyes into maya 2009 and its tracked good the image sequence automatically appears, but the grid isnt on the ground.. (which is of course normal) so i move the camera to make the grid match the ground, but when i move to the next frame the grid just goes right back to its original spot.. What do i do? i dont want to manually move the camera in the same spot for every frame..

Edit: Quick thing is there a way to move the camera around without just rotating it around? Like when you alt+click it rotates it around, what do i press and click to move around on xyz and not rotate?
