You should benefit from adding more RAM. How much is hard to say but at least to 8 GBs. You might know more if you observed your memory usage in Activity Monitor.
About OS X Memory Management and Usage
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.
Adding RAM only makes it possible to run more programs concurrently. It doesn't speed up the computer nor make games run faster. What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent. It will improve the performance of applications that run mostly in RAM or when loading programs.

Okay, I only have 187 mb free when I am running just Final Cut Pro. So I could def. benefit from a RAM upgrade, right?

Generally, if you find not much free RAM and the computer seems to get sluggish, then more RAM will definitely be helpful. If you wish a more technical view then monitor the PageOuts() figure in Activity Monitor. If you see positive and growing figures in the parentheses, then you are running out of RAM and need to add more.
8 GBs may be fine, 16 GBs may be overkill, but that's difficult to assess until you actually have 8 GBs installed or someone drops in here and says they run the same applications concurrently and needed more than 8 GBs.
Tom Wolsky, who is a renowned expert in the areas of the programs you use, has suggested 16 GBs will not be overkill. I'd say that's good information.
