You won't be able to upgrade anything but the RAM and HDD in that laptop.
Aside from that, the GPU you picked out is a desktop model anyway and the CPU wouldn't ever be compatible even if it WAS possible to replace it because it's a totally different generation and socket.
For the RAM, you need to make sure that it's laptop RAM and not desktop RAM, as well.
The Processor is the Mobility version, made for notebooks. The RAM is also compatible...now, where do I go with this? Could I do the upgrade if I purchased a new motherboard with the proper sockets?
