That short white piping off of the T & P valve needs to be copper and go down almost to the floor.
Is that a BX connector on your NM cable there ?
I don't see a problem with the pex but I'm sure others will chime in.

Connections to the heater is supposed to have a ninimum of 18" copper I believe before any transition to pex...

I use these. They seem to clear the body and have a metal attachment point that can be removed.

The pex here is the cold water pipe to a bottom inlet.
Just worried if it needs support and whether it's too close to heat from top of heater?
What's a bx connector? The one I have is a plastic one.

Without a doubt support any pipe to where it is straight into a pex or sharkbite fitting. Pex is OK across the tank, just not pretty 
The electrical connector you have going into the water heater pecker head does not have a strain relief on it, and is made for BX. Yours should look like this, or metal with screw strain reliefs.

Attach a block of wood to your stair riser and use a clamp to hold the pex in the proper position. As far as the strain relief, you are missing a collar and possibly an insert to make the connection solid. You don't have anything that will keep a good sharp tug from disconnecting the wires inside. Here are your strain relief with the cap applied and a screw type strain relief.

And what's a strain? Why is the plastic for the nmd cable bad?
