Check the manual for cruise settings and leaning for 10000 feet as well as climb settings and use those.
10000 feet in itself is not relevant to icing, temperature is, pedantic maybe but you can takeoff on a hot day of 32 deg C and be well in the plus at 10000feet yet takeoff on a cold 4 deg C day and have icing problems at 4000 feet and none at 10000 feet.
In most circumstances icing will not be a problem unless flying in visible moisture ie clouds.
No do not just close the throttle and descend. Try for a managed cruise power descent or reduced power descent rather than closed throttle.
Monitor the manifold pressure which will increase in a normally aspirated engine as you descend and reduce accordingly.
Monitor the speed in the descent keeping it in the green arc. Only go into the yellow arc if the air is smooth and you are sure it will stay that way.
IAS will decrease as you climb TAS will increase so be aware of that fact.
As CanadaAir stated your climb rate will decrease as you climb higher do not be tempted to pull back chasing the climb rate or you will get into a high angle of attack high drag situation. Hot days and heavy and you may struggle with a normally aspirated engine so precise flying is more important at altitude.
Finally while you should not have a problem at 10000 feet with lack of oxygen, a small minority do. Above 5000 feet and night vision suffers which shows there is an effect how much depends on your fitness lifestyle and natural tolerance.
If unsure go for your first high altitude climb with an instructor.
