One of the challenges with the poetry of e. e. cummings is to achieve precisely what you have mentioned - it is difficult to break it down into logical sentence structure. Obviously you might come up with some different answers but here is a suggestion to get you started:
Since feeling is first who pays any attention to teh syntax of things will never wholly kiss you.
Wholly to be a fool whilst Sprin is in the world.
My blood approves, and kisses are a beter fate than wisdom.
Lady I swear by all flowers.
Don't cry - the best gesture of my brain is less that your eyelids' flutter which says we are for each other.
Then laugh, leaning back in my arms.
For life's not a paragraph and death I think is no paranthesis.
Hope this helps!
