I currently have a raspberry Pi 2B with a 64GB Lexar USB 3.0 jumpdrive, it's already pretty fast, but I'm wondering if I can bypass some of the bottlenecks in the system by using te x600 expansion board (link) with a 2 500GB HDD's attached in LVM, or should I just use 2 USB to SATA adapters?

I also want to attach a USB 3.0 Gigabit ethernet adapter. The device will be directly connected to the router and streaming only happens over LAN (plex).

The device is currently running in Turbo mode (1Ghz) and is running plex, a samba share, couchpotato, sickrage and Deluge.

Is this a good setup, and does anyone have suggestions to improve?

Thanks in advance!

It appears that the data links are just going through one of the pi's existing USB ports via an adapter. The GPIOs passed through are presumably not used for anything (trying to use them to implement > USB 2.0 speeds would I think be futile anyway). This means you are still limited the same way. You could now attach a SATA drive, but it won't be working at SATA speeds.

will a normal HDD speed it up

No. Any drive or stick you attach will operate at USB 2.0 speeds.

I also want to attach a USB 3.0 Gigabit ethernet adapter.

You could (in theory), get a faster ethernet connection this way (although you do not need that board to do so) since the max rate of the USB bus is probably ~280 Mbps whereas the existing ethernet is 100 Mbps.

That ~280 Mbps USB 2.0 speed (which your benchmark is within) would include both the ethernet and any connected drive. It is not per port, it is in total. Note that this is true with or without an additional adapter, since the ethernet and USB jacks use an integrated controller.
