I watched a video saying to get a molex cable for my cpu fan because your motherboard doesnt alwa was told to get this because it's safer and you plug it in directly to your power supply. Is this correct?

The cpu fan should ALWAYS be connected to the motherboard so the system can monitor the fan operation and speed to control cpu cooling.

can you get rid of 2 pins so its a 6 pin power cord?

Do not know. If you trying to adapt 6 pin pci-e graphic card you might look at this. Dual 4 Pin Molex IDE to 6 Pin PCI-E Graphic Brand New High Quality Card Power Connector Cable Adapter, Item#: 9SIA76H2J29407

Do you have to use both the molex connector and the 4 pin connector to be able to use the 8 pin connector, or can you just use the molex connector to be able to use the 8 pin connector?

You need to use both the molex and the 4pin.

can you use this cable on both 4 pin + 8 pin = 12 pins , motherboard it supports the full 12v..?

The product provides an economical way to upgrade a system without having to replace an older power supply and is compatible with motherboards, with a voltage rating of 12 V DC.
