The colonial interests of Russian Empire lie elsewhere - notably in Central Asia (as has been already pointed out in the answer by @FelixGoldberg). In part this was due to geographic and historical factors, but also due to the competition with other colonial powers, notably Britain and France. Just to give a few points (a rather incomplete list):

During this time Russia was already engaged in a colonial enterprise on a staggering scale - the conquest of Central Asia. Conquering and then digesting such a vast territory more or less took up most of Russia's attention and resources available for colonization.

You got your facts wrong.
Russia had (and has) great resources, but always had (and has) problems monetizing them. They didn't sell Alaska for pennies on the dollar because they are such generous people, but because they desperately needed the cash. Especially after loosing the Crimean War in 1856. That's probably the reason why they sold it to the USA, not to Great Britain.
Russia doesn't have too many warm water ports. Maritime trade never has been that important for Russia. Today the sanctions they face would cripple any other nation, but Russia seems to endure it. Why? Because it doesn't really need outside resources.
Apart from that, they already had a colony. The largest in the world, it's called Siberia.
Even so, a Mr. Nicolas Ivanovitch Achinoff did try to set up a colony in Africa, in Somaliland. His colonial experiment was not supported by the Russian government, and wasn't successful.
