Wanting to get back to 1.x way of displaying "Custom Fields" in Classic theme

Recently upgraded to G2 and I am amazed by it. There are a few things that bug me that I want to customize but the first one I to tackle is the way that Custom Fields are displayed. I don't like how it says "Custom Fields" before displaying the custom fields, and also I don't like how the titles of custom fields aren't bolded. In other words, I want to display them as they appeared in 1.x.

I was also having trouble with the custom fields that were imported from my G1 gallery. After they were imported I couldn't seem to get rid of the titles if I wanted to use the new G2 custom fields that I created.

And lastly, when entering custom fields there is only a 1 line box available to enter the info. Since I often enter alot of info I would like to change the boxes to make them a few lines long, would this be possible?

Thanks to anyone interested in helping me out.
