The FMS uses a flight path angle but it will indicate the VS required at TOD.
The seats, unless it's an option, have electric motors for vertical adjustment. Make sure your headset lead is not under, near to or around the gubbins under the seat or you'll chop the lead in half when you motor it.
The jumpseat is stowed behind the captains seat and can prevent the DV window from opening fully if it's incorrectly stowed (it's not obvious either way when it is stowed though).
There is a null area on the pedestal lighting adjustment knob. In bright/day light it can look as if your audio panels have lost power. Give the knob a wiggle or turn it up.
Reliability is top notch. I only had one no go in over four years.
Bleeds are occasionally temperamental but reliability has improved greatly and they usually give you a hint before they go pop, like Toffair mentioned.
No drama with electrical reliability.
The loadies hate the holds, low and dark so they appreciate it if you can leave the power on while they're doing their thing.
If the EICAS doesn't declutter airborne then you've either forgotten something silly, something has exceeded a limit or you've pressed the EICAS full button. Best to check carefully because things like the APU box are small and tend to blend in rather well.
The CCD can get a bit jittery sometimes so if you need to scroll up and down it's a good idea to use a finger on each side of the CCD pad, seems to desensitise it a bit.
Enjoy.
