Font in main sidebar

Firstly - great job guys, awesome theme ! We're building a small website for our kindergartens ( http://lasteaiad.rae.ee/ )and need some tricky css magic to get it to work like we want. Tried tens and tens of different themes, until found Your awesome Evolution theme. Couple of questions: 1. When clicking on a menu item, the page refreshes and jumps to the top. Can this be avoided (maybe in Pro version)? 2. How to change the font size on category menu items on the main sidebar (currently titled "Vali lasteaed") 3. Is it possible to use a different header image on each category page ? So that every kindergarten gets her own header image. We tried "Unique header" plugin ( http://geek.ryanhellyer.net/products/unique-headers/ ) with Taxonomy, but didn't work. The Pro version seems to have a random header option, but is there a specific header option possible ? Maybe just point us where the code lies and we'll figure it out ourselves... 4. We want to use Easy Responcive Tabs plugin in our posts (like in http://lasteaiad.rae.ee/category/aruheina/ ), but we need to remove the padding, so that the tabs start from the very top of the post PS - we probably want to go Pro - will it overwrite all our settings that we've made so far using the free theme? Or is it a simple upgrade...
