Please do not install bumblebee, it was replaced by nvidia-prime to switch between graphics,
nvidia-prime should have been installed automatically when you installed the NVIDIA drivers.
In case this did not happen, you can install nvidia-prime by opening a terminal and executing :
sudo apt-get update
sudo apt-get install nvidia-prime
TLP is something completely different - it is a tool you can use to optimize power consumption.
So you can install both tools, nvidia-prime to switch between graphics and TLP to tweak power.
Switch between the intel and NVIDIA graphics with NVIDIA X Server Settings -> PRIME Profiles.
