You don't need the routers to be connected directly to track interfaces to lower priorities, GLBP will compare priorities on all routers on the same GLBP group to designate the AVG and AVFs. This conversation will go through the switch like any other traffic (routing protocols, cdp, hsrp, vrrp, etc..)

By default, GLBP uses round robin and you can see the options with the command:

glbp 1 load-balancing ?

You can use:

glbp 1 weighting

to set up maximum values, certain tracking for interfaces (if an interface fails how much weight to reduce, or if another router fails, how much weight to take, there's lower and upper bounds on the weight, etc).. it's a lot of criteria, you might wanna play around with those options a bit
