Is it normal to find spider cracks in the SMC around the motor mounts on a 10 year old hull? They are only on the inside, and I'm thinking I need a layer of glass down there now.

I know the cracks you are talking about...I've had boats with them before. I think it is a common thing. I never worried about it but I am not too hard on my boats unlike some others here. Guess it depends on your riding style, but another layer of glass wouldn;t hurt anything.

I plan to be hard on it, looks like some 8.5oz twill will be going down.

The 94 sq nose i am building has all the same "damage" as yours. I don't feel that it is much of a issue at all, but I am reinforcing with 3 layers of 5.5oz carbon/kevlar just to be safe.

I would recomend going for the 8.9 oz S-glass satin weave that US composites sells. Keep the resin ratio low with a squegy. It will be very strong, and lighter weight then standard e-glass.

I was planning on 12 oz biax on the sides with the 8.5 over that, and one layer of 8.5 on the bottom (post 10).

I'm really not overly concerned about the weight, were talking maybe a pound or 2 and I weigh only 150. More interested in total package strength, and didn't see any need to be doing carbon at over $50/yd. That twill with black resin is going to look sharp, and should conform easily around motor mounts and such. Thats one reason I decided to stay with 4 pound foam in the back, after seeing how thin the deck is. I fully intend to beat the crap out of it in the surf, don't want to regret not making it strong enough to last a few years.
