You are exactly my measurements. Although I fluctuate between 175 - 185lbs
I ride 158 for all-mountain. 161 is great for powder days, but with rocker you definitely won't need one that big. You can even do a 156 for a more playful board.
Here are my recs:
Burton: Custom X - Great board for your style of riding. It is a traditional camber and fairly stiff and light. You're going to love charging with this board.

Ride: Highlife - I haven't had a chance to demo this board, but I have heard great reviews from co-workers. They said this board rips and is a fantastic all-mountain/powder board. It has a LowPro rocker. That means it is rockered through the tip, but flatter in the tail. I hear riding switch is fine on this board, but it's not exactly what it was built for.

Lib Tech: Banana Magic - I friggen love this board. If budget was not an issue, this would be my board for sure. It was a pure pleasure to ride this board all-mountain while still being able to freestyle. It was light and fast. Edge to edge was smooth and the power out of the turns was satisfying. It is also a rocker with magnatraction. This board has the highest rocker out of my recommendations, but it doesn't ride like one. It's loose when you need it to be yet still engaging during carves. The magnatraction absolutely works on icey conditions.
T-Rice Pro Model - It's hard to find a bad review about this board. I unfortunately didn't get a chance to hop on one, but people love it!

K2: Turbo Dream - I will always recommend this board for an all-mountain rider. It is simply a great board to shred the whole mountain with. This board has K2's all-mountain rocker which is the rocker tech that I favor most currently. Engaging edge hold, great torsional flex to power you out of the turns, and the 2011 has harshmellow which dampens the ride on faster, steeper runs. Oh, and landings were stable off natural kickers (Not that I get huge cork 360s or anything :P). For a rockered board, the Turbo Dream was pretty fast. Not Custom X fast, but fast enough.
Slayblade - Another employee favorite at the 2011 test fest. This one has 0 camber which means that it is totally flat. Pretty decent stick in my opinion. Zippy and gripping. Smooth edge to edge and decent pop.
For bindings, your options are wide open.
You want stiff? Ride SPI are super stiff. You want middle of the road flex? Ride Deltas are great.
Rome Targas have stiffness adjustability so those are a great choice for all-mountain riders.
There are tons of recent binding threads around here so you can take a looksy there.
