Installing wall plate will look a whole lot better. I haven't read much problem using interconnects when it's properly connected with quality materials. no need for monster cable price of course.
www.partsexpress.com and www.monoprice.com will be ideal places to find necessary parts and inexpensive too.
however, do you plan on mounting the surrounds over the wire outlet hole? Is the speaker big enough to cover the whole installer made? if that's the case then wallplate won't be necessary, just patch up the hole wiht some putty/caulk if it's not too big. that'll just be your personal preference.
You could do without using interconnects once the wall plates are up, bare wire would do. just make sure non of the wires are crosses when putting it all together.
