Performance

I'm developing a single page application with a lot of css & javascript. For now the page is 1.3Mo composed by 5 section. Here are the rounded stats :

Document : 10kb
Style : 60kb
Images : 450 kb (already compressed, include a big gallery thumbnails)
Javascript : 700kb - 600kb of "framework" (jquery, jquery-ui, boostrap, modernizer, waypoint, ...) and 100kb of custom js.
Fonts : 125kb

And the site is not finished yet. (Will include gmap api, and some others...)

My questions are :

Do you have any statistics about the average weight of an SPA?
As this is the whole website, do you think it's acceptable?
Is lazy load (for images) a solution?
What will be impact for SEO ? Is the "200kb rule" of google still relevant?
Do you know great tools to detect which javascript code is not used during the the exection of a page and then the availability to optimize these 700kb of framework js stuffs?
Can a caching strategy be an answer?
