Time to change

First heres a list of what I have

Onyko TXRZ920

Mirage towers Omni polar (I think) X4: Mirage Sub dual 16", Mirage center channel.  (Ill have to get exact model #'s later

Monster HTS5100 & avr2000

Old Sharp Aquos Quattron. 70"

I'm at the point where I don't want to run wires anymore and maybe looking just to simplify things with a new TV and a decent soundbar and wireless sub.  

I haven't really kept up with anything new in th epast 5-7 years and looking for recommendations and just a a cleaner set up by (decluttering) a lot of the big componets.  

Would appreciate some insite and recommendations.
