No.
If really worried just touch a bare metal part of a radiator.
Handle the motherboard, ram and CPU by the edges where possible.
Try to avoid contact with the CPU and ram pins.
The ram will only slot in one way around, it has a little notch along the bottom between the connection pins.
The CPU will only fit it one way, lift the lever on the side of the socket, look at the socket and you will see certain pin holes are blank, along the edge some pins are missing in the corners, this corresponds to the pins missing on the CPU, it will drop in easily, don't force it in, close the lever down.
The heatsink has a plastic guard protecting the paste, remove it.
