How long does a hugel bed last before it needs to be rebuilt?
Are some types of wood better than others?
Are some types of wood better for different crops?
Does the direction of wood grain have any effect on the system?
Is there an advantage or method for preparing the wood before burial?

Sounds like a good set of resources to work with.
The sawdust might absorb nitrogen too quickly to be directly of use in a garden bed. If it's coarse enough to safely use as animal bedding, or if it would be worth the effort to sift and/or agglomerate, you might try lending it to someone near you who keeps domestic animals. There are other ways to diminish the C:N ratio (or just the activity of the carbon) before using it, such as growing mushrooms, cold-composting with N-fixing bacteria, or low-temperature pyrolysis.
The extra bark, rotten portions, and maybe even the charred portions will help make the wood less of an immediate drain on fertility.
It's possible that some of the plants you would want to grow, won't do well on pine for the first few years. It's worthwhile to plant a wide variety anyhow, and other people here might have some good advice on what to try.
how do you harvest and renew bark without harvesting and renewing the hardwood?
