B) Content-Aware will be your best friend. Below I'll show you why.
Got your Spot Healing Brush Tool set to Content-Aware? Great!
Now, simply find a scratch, dust, rip and left click and drag over to fix it. But hold on! Before you move to a new spot, stop dragging and start over.

If these tools aren't giving you the results you want, you'll need to use the Clone Stamp Tool. This tool is used for more refined areas such as faces, and other tight corners.
You can find the Cone Stamp Tool in your Tool bar...

That's next...
