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..
