Documentation?

I went to http://ideaboxthemes.com/themes/tatva-lite-wordpress-theme but I can’t find any documentation for this theme. I have so many questions.

1. I would like the logo to be the proper size of 800×300 — is this possible?
2. Where can I find the icons for the homepage widgets?
3. How can I adjust the homepage product image containers to accommodate a vertical format? Or, move the buy buttons over closer (or under) the product images.
4. Store page button does not show text.
5. I’m a bit confused between EDD store and EDD Front page. If the homepage is set to Store, do those setting override the Front Page settings?

There will no doubt be more questions 😉
