Does anyone know if there is a setting in the BIOS of a T310 that will cause the computer to automatically start if it gets power?
Yes, there is an option in the system BIOS that will do that. It is under the System Security section. The option is called AC Power Recovery. The default option is Last, and that is the way you are wanting it to be configured. If you have not changed that BIOS setting then the default behavior of the system will be to power on when power is restored.
The AC Power Recovery is only used when the system is improperly shut down due to sudden power loss. If any form of shutdown command is used to turn the system off then when power is restored it will not use AC Power Recovery, so it will not power back on.
We are thinking of purchasing a power switch for our servers which can be controlled remotely. This is a simple switch which allows you to connect to it over a network and turn individual power outlets on and off.
That is a really bad idea.
What you are proposing is the same as pulling the power cord out of the computer to turn it off. Technology has advanced to a point that computers are better able to handle sudden power loss without damaging HDD platters, overheating, or many other possible issues that can occur from sudden power loss. That does not mean it can't or won't happen, it just means it is less frequent now. Your likelihood of data loss/corruption or hardware failures will increase substantially the more often you shut the server down by that method.
I would recommend that you find another method to perform this action. One idea is to use the iDRAC to power on the system. You will likely need an express version of the iDRAC to do it, but you should be able to SSH in and run this racadm command:
racadm serveraction powerdown
You can also run powerup, powerstatus, and many other commands. You can read more about these features in the iDRAC and RACADM manuals:

In that case it will not work for us as the servers will be started from proper shutdowns.

Sorry for the misunderstanding - we would never simply unplug the computer just as we would never simply turn off a power outlet if there was a computer running on it. We would shut down the computer first, then turn the outlet off.

I've heard about iDRAC - is it a hardware solution, like an add-on card? What about power consumption - is that anything to worry about or are there green options? Thanks

Yes, it is a hardware option. It is an optional accessory that takes over as the systems baseboard management controller and adds additional management functionality. It uses very little power. You can read more in the above link I provided.
