the best advice at this point is to just get the equipment and use the interconnects that come with it (or get some from monoprice.com) and for speaker wire, go to home depot or Lowe's and get 16 or 14 gauge twinlead wire.

after you are ready to upgrade your equipment to separates of good pedigree (that may take a while), then and only then try some more premium wires in the less than $100 per pair and preferably less to see IF yo hear an improvement.

of speaker wire upgrade, audioquest makes type 4 which is very affordable and sounds very good.
