Custom Template Fixes / Google Feed Fix

I have a website which requires a few fixes with the template. In short, buttons need to be re-alighed, font needs to be fixed. Some fonts are way oversized, and need to be smaller. Also, various buttons need to be aligned. I would like to have a Grid View by default for all products. If you know how to integrate K2 plugin with Joomla and jQuery, that would be required as well. Finally, after migration to MijoShop, google feed stopped working and google stopped displaying the products. I would need it fixed as well. After migrating from AceShop to MijoShop, my custom search stopped working. In the past, I was able to sort the items by: MEN/WOMEN, color, price (dragging the bar), style, e.t.c - which came from attributes. Now I get Page Cannot Be Displayed 404 error.
