Building through the mail???

Being in a small town I have no dealers I can audition products through, and travel for me is quite difficult with job, kids etc... So, after a couple months reading all I can here as well as other sources, I've decided I'll have to mail order everything and hope for the best. This is my first attempt at hi-fi so I'm almost positive that my ears will like it as I know no different.
I'm not going real big on the spending as I cannot afford the high dollar eqipment.
Here is what I think may go well together:
Roksan Kandy iii int. amp with matching cdp
Paradigm studio 60 v3's
A pair of Paradigm servo 15 subs, or Velodyne DD15s
I am hoping for a mild top end with the paradigms, and some spl in the room(the reason for 2 subs).
If you have any advice for me I'd be more than happy to here from you.

Thanks
Shawn
