The code now requires that you run a ground conductor from the service to each sub panel. Grounding and bonding at each sub panel is no longer permitted. Your ground rods and bonding with the neutral should only be done at the main service which sounds like it will be in the shop. It is very important that all the sub panels have the neutrals and grounds seperated on different terminal bars and that they NOT be interconnected or bonded. If you are reusing existing equipment in the other buildings they may have to be rewired to make sure this is done. Not a big job but a big deal. The size of the ground conductor will be based on the size of the breaker feeding each panel.(Table 250.122 in the NEC) You can find information about all this in Article 250 of the NEC. I would encourage you to upsize the conductor for the ground. Also, if your runs to the other buildings are very long you may want to calculate voltage drop and consider upsizing those as well.
It sounds like you are aware of the importance of grounding. Bonding is a little more complicated. You may want to have a licensed electrician take a look at your job when it is done.
Also, you can find a lot of information on grounding agricultural buildings on the internet. Stray voltages seem to bother cattle and horses more than other stock and some of the soloutions need to be done during construction such as grounding mats in concrete and such. Attention to grounding what is there will likely solve most of your problems.
I got called to a farm one time for a service call. The guys hogs were dying for no apparent reason. Turned out that improper grounding and bonding (along with an underground splice made in a coffee can filled with tar)had electrified all of the metal siding on his barn and when the hogs bushed against it with their feet grounded in the wet dirt they were freezer bound. Lucky it wasn"t him.

Today's Featured Article - New Life for an Old Allis - by Tyler Woods. My friend Jon, has an old '39 Allis Chalmers B. He thought it a marginal tractor that had long since served its time. She smoked terribly and never had much power but he couldn't afford another so he was limping along with what he had. Jon's Allis has a small front loader and though it doesn't carry much, it serves his needs. It was the hard starting and low power that made him think it was time to replace the old girl. Jon called me to help him discover why his tractor wouldn't start
