Kale pro widget and font issues

Hi there
I have just upgraded from Kale free to pro version and it’s great, I just have a few teething issues I want to iron out:

1. If I tick “show thumbnails” in the Related Posts customize editor, it only shows up with text instead of thumbnail imagery. How can I get an image to show up with the title of the post? (you can see an example here that has the titles that I want to add images to here: http://am-to-pm.com/monday-coffee-kyoto/)

2. How can I edit the “about me” widget so that it looks more like the Demo version you use for Kale? When I use it the image takes up the whole sidebar but I want a smaller image in that space. Can I also make the text smaller in that space?

3. The links referring readers at the end of the post to the previous or next blog post – is there code to make that text bigger?

4. Finally, I installed Jetpack as recommended to get the “share this” icons but the icons for Facebook, LinkedIn and Pinterest are wrong. How can I fix that? (you can click that earlier link again to see an example)

Any help on the above questions would be very much appreciated!

Thank you,
Kate
