Few ? 's

Ok I seen the price drop on the v console and the v 700r,  I am going to buy the both the v700r and v 700c but I dont have all the cash at hand to buy both, been spending more than I though in setting up my other studio room. 
 question. is can I use the v 700r as my audio interface for the time being and use my tascam fw 1884 as a control surface, I would think I can all I should have to do is choose the v700 r as audio options and fw as control surface.. just wanna make sure..dont want to keep one in the box  till the other arrives.
 second question, doses the 700r or 700c come with sonar 8.5 PE or dose it just come with v 700 .. 

Third question is the v 700 only usable as a sound card for sonar Only? cus I got mixed answers about that..

I have a few different Sound cards.. 

Ok thanks Brandon.. Headphone jack is not a problem right now, Main volume shouldn't be an issue either as long as the virtual main works on the Mixer section of sonar. I think with that said I think Im going to buy the V 700 c first and use one of my usb Sound cards for the time being. I have a stanton Scratch open amp , asio drivers, and a NI Kore first edition, and a NI audio 4 card..I am going to use one of those for the time being, I have delta 10/10 pci card which I cant use cause new computer has pci Express.ordering board right now :)
