Ibn Taymiyyah said:

"It is obligatory to know that the office in charge of commanding over the people (ie: the post of the Khaleefah) is one of the greatest obligations of the Deen. In fact, there is no establishment of the Deen except by it....this is the opinion of the salaf, such as al-Fadl ibn 'Iyaad, Ahmad ibn Hanbal and others"

What or are there any conditions that have to be in place and fullfilled prior to establishing the office of the Khalifa, or is the establisement of the office a priority that takes precedence over all other needs of the society?

Good question. I am not a scholar myself but I think that establishing a khilafat is as important if not more as establishing any other form of government. You need a stable government for any country to function, so I think that a muslim state needs an islamic head. Although you will find many muslim countries that function well even in democracy e.g. malaysia, I think what the sheikh is saying is that as muslim individual it essential for any muslim sovereign state to be governed in accordance with the shariah, and this in turn means establishing a khalif as head of the ummah. Any other form of Governance is sin, essentially that is what he is saying.
