I have a drawing I created from a scan. I selected its marks using channels and extracted as much as I could get. But I still have textures from the paper. Is there a nice way to remove them to get the cleanest drawing yet still have it representational to the medium? Thank you.

What exactly you want to remove? You can use mask, or any other technique like Curves adjustment to deal with grey values on your scan.
Could you please post the unedited image.
You can try making several scans, rotating the original in the scanner, then combing the images.
It is suppose to even out shadowing of the paper texture. By rotating the original and blending the scans with lighten mode, it fills in the shadows. However, if you're working with a photo of a drawing, and not the original drawing, that will not work.
You could try »stepped« Adjustments.
The most important thing here is to even out the light, then set the white point.
With that done, you may not need to do anything more, except perhaps some spotting.
Whatever you do, don't start with selecting and masking the drawing! That will get you down the wrong track and quickly into a lot of trouble.
Here's what you can do with general and global adjustments, without any masking of the drawing itself:
Here's the layer setup. In chronological order, bottom to top:
