Thomas Eliot works multiple themes in the poem, however in general, his usage of imagery mainly represents ageing and decay. In the lines "When the evening is spread out against the sky / Like a patient etherized upon a table", the phrases like "sawdust restaurants" and "cheap hotels," the yellow fog, and the afternoon "Asleep...tired... or it malingers", represent decay. The character's concerns about his hair and teeth which is mentioned in the lines "Combing the white hair of the waves blown back / When the wind blows the water white and black," show the problems about aging.

It's tirade because a tirade is an angry, long, bitter speech or outburst.
It really depends on which poem you are referring to. If it's by Langston Hughes, then I'd say it's free verse.
Free verse means there are no rules here - the poet is not using any strict meter (pentameter, or such), and there are usually no rhymes. Since this is the case, ballad, lyric, and blank verse cannot be correct because they all have a strict poetic form to follow.
A common theme is cultural integrity.
