Translating a quote about Zhuge Liang "淡泊名利才能显示出自己高尚的志趣，保持心态平和宁静才能在思想上达到高远的境界。这是诸葛亮表达自己作为一个读书人志趣清高的名言，被历来的读书人所推崇。尽管不少人汲汲于名利焦头烂额，但其照样可以请人将此言书写悬于客厅，以显示自己志趣的不同凡俗."

I've been trying to 'block' this according to its syntax units, but I keep getting stumped.  


What does 志趣 mean here?  (nciku gives it as 'aspiration,' but that doesn't seem appropriate in this context. 
"这是诸葛亮表达自己作为一个读书人志趣清高的名言" Does this mean that Zhuge Liang regards HIMSELF as a scholar?  Again, the 志趣 is confusing me.
What does 其 refer to here?
What would be a decent translation for these three sentences?  Everything I've attempted so far sounds terribly awkward.


Thank you for your time.

志趣 can be understood as 志向（your goal/dream） 和 兴趣 (things you are interested in). Your goal/dream is often the things you are interested in. So, 志趣 conveys the sense, kind of combination of 'goal/thing you're interested in'.
这是诸葛亮表达自己作为一个读书人志趣清高的名言. The main body of the sentence is 这是名言. '诸葛亮表达自己作为一个读书人志趣清高的' is attributive to 名言。Well, "诸葛亮表达自己作为一个读书人志趣清高" itself is a sentence too and its main body is 诸葛亮(subject)表达(verb)志趣清高(object). 自己作为一个读书人(himself as a scholar/reader) is an adverbial phrase. As for 志趣， refer to '1'.
其 is a personal pronoun. Here means 他们 the substitute of 不少人, which is mentioned in '尽管不少人汲汲于名利焦头烂额'.
Someone already did the translation in the comment above.
