Modifications to Product Detail Page

[mesquite_murph]

I have three modifications I'd like to make to the products detail page.

1) resize the product image to fit the image box
2) resize the product name font
3) turn off the product image magnifier

I've attached a snapshot of the screen for reference purposes. website url is www.murphycofutures.com, working in child theme.

Thanks in advance for the assist.
