Yes, the males have hooks. I am not sure what you are asking about the book lungs, sorry.

Grammostola rosea mature males have tibial spurs

The booklungs look like four little squares that are lighter colored than the rest of the tarantula, and can be found on the ventral side of the abdomen, toward the cephalothorax.

Some tarantulas are easy to sex this way while others aren't. Males possess special hairs between the upper pair of book lungs that they use to make their sperm web. These can be seen in the form of a small black triangle or patch of black on some species, between those upper two lungs. The females do not have the patch.

when you say "upper" do you mean anterior or do you mean posterior?

If you have a male you will definitly notice them. They are avarage size. Also look to see if the pedi palps, are larger.
