You are going to get a Mac Flapping problem with Active/Active on the server(NIC teaming). Why?
1. Blade Switch is just a switch. Unless you can stack(real) them together to ack as just one switch. It think it doesn't support.
2. You can group uplinks from blade switch to C3750 with LACP features.
3. However, traffic from the server will go through C3750 with 2 paths. This is a problem.
I'd recommend you to use Active/Standby on the Server and do link-state tracking on Blade Switch. In case you lost the uplinks the server should know how to use another one by using this features. It's going to down all downlinks on the server when uplinks were down.
