You should be using only the D-Link DAP-1522. Nothing more. If all your computers are capable of Wi-Fi, there should be no bridges. If you want to connect a wired-Ethernet-only computer, you can plug it into the DAP. If you want to add a bridge of your own, okay, but you're on your own for configuring it.

Why would we run one as an access point at practice but as a bridge during competition? That violates my "Practice like you want to perform" rule.

During competition, the access point is provided by the Field Management System. During development, there is no FMS, and the DAP must be in Access Point mode in order to connect the Driver Station to the robot.

The classmate can connect directly to the white DLink (ping) through the internal wifi card.

Sure it can. If
yours does not, there is likely a misconfiguration somewhere. Your D-Link DAP should be set in Access Point mode, with its SSID set to your team number, and wireless security disabled. The Driver Station software configures the Classmate networking appropriately, based on the team number you provide to it.

I'm having a hard time understanding what the blue/black linksys is supposed to be doing at a high level though. I know it's supposed to provide better power for the classmate but is it acting as a bridge or what?

Last year's Linksys router is not used this year.
If you want to play around with alternate (and unsupported) network configurations, it should be possible to use the old blue Linksys as a fixed access point with your team number as its SSID on the 2.4 GHz band, configure the D-Link as a bridge to the wireless network thus created, and make sure everything is set to the appropriate IP addresses (similar to last year's setup). But you should first configure things as directed in the "How to" documents and get them to work the way they are supposed to, before starting any hacking.
