We have 32 data gathering sources all operating at 100Mb. They tie to a single server.
Currently, we're using a 100 Mb network.

We've have 2 Trendnet TEG-424WS units we can put in. They come with 24x100Mb ports and 4x1Gb uplinks.
Can we tie the server to one of the GB up-link spots and have it get the benefit of the full 1Gb (or a reasonable approximation) or will we be stuck with the server only getting 100Mb with each data source taking a turn to talk to it, one at a time.

"Try it and see" is not an option.

That Trendnet's 4 Gig ports can be used as normal ports. See below:

24 x 10/100Mbps Auto-MDIX Fast Ethernet ports
4 x 10/100/1000Mbps Auto-MDIX Gigabit ports

They are referred to as 'uplink ports' probably because when this router was released, 100 to hosts was the norm. 1 Gig was 'reserved' for connections between switches.

You should be ok.
