Congrats!
Congratulations and best of luck! The King Air is a very solid, pilot-friendly airplane. It may not be the speediest bird around, but it will do most anything asked of it. I fly a 200 corporate, and am very much enjoying it.
Previous post right on about ice vanes ... essentially doors in the intake that open and allow ice chunks to flow straight out the bottom of the nacelle instead of making the 180 in to the compressor (remember, the PT-6 is reverse-flow, so the compressor is in the back and the exhaust is up front by the prop!). Remember that, due to the power loss mentioned, you will suffer a small true airspeed penalty when the vanes are extended.
Best advice I can offer is to fly the numbers ... the climb speed schedule works great, and even at gross I'm doing 1000 fpm until above FL200. Nail your ref speed on final ... KA lands great (but flat compared to the pistons!) unless you're carrying extra speed ... then it'll float all day long.
In response to another post, yes, the 350 requires a type. The 200's MGTOW is 12,500, making it the heaviest non-type KA ... the 300/350 requires a type ... the type is common to both, if I'm not mistaken.
Tailwinds, y'all ....
