A.Can I upgrade my processor? If yes, will the TL 64 work?
B. How much more RAM can I add to my laptop?
C. Can I upgrade my graphics card? If yes, which graphics card capable of playing HD movies would be the best pick?

Essentially, upgrading a laptop is near to impossible. You cant modify the ram of the computer by adding or removing ram and You cant for the processor because laptop processors are different from desktop processors and you cant replace them. However, If you can find a pci-e to usb, you could potentially have an external GPU for your current build, but it isn't recommended because laptops arent built for that and your cpu might bottleneck it.
