The Simple Harmonius Ring is a great buy, and you can supplement it with the free 489 ring at Klaxxi Exalted. The Shadow Pan trinket isn't terrible if you don't have the money for a Relic of Yu'lon. The Klaxxi neck is also hard to pass up.
If you're killing Sha of Anger every week I would avoid hands and legs, as you should eventually get your tier pieces this way.
At the end of the day, it will ultimately come down to which pieces are holding you back the most.
One caveat...If there's nothing you need especially badly, you may benefit the most from hoarding your valor for now - New 496 valor items will be available in 5.1.
