0.  There are so many ways of translating your title.  "My life is brilliant" is very bland and uninteresting.  "The brilliance of my life" sounds better to an English speaker but the title does not really match what is being said in the poem.  Another one comes to my mind is "The Colors in My life" also with a hint of sarcasm in it.

1.  To make your writing more interesting.  You can write something like "My love is pure.  It's simple as that".

2.  Plan is 計劃.  That would make you sound sinister.  Opinion is a better word. 

3.  Read my essay/translation on "Kingdom & The Beauty" in http://jeffican.bokee.com

4.  Actually what you wrote is the brilliant intensity of the mutual gaze.  However, it is more appropriate in English to use "fire" as it hints of passion to an English speaker.
