I have had a look in to this system for you and I can guarantee that it does support 16GB and also our SSD's. We don't actually provide hybrid drives so I would be unable to guarantee they are compatible but as they run on a SATA connection you should have no problem at all.
We would also be unable to confirm if upgrading the system would void the warranty as the warranty is different in each system. I would check your warranty details to see if it would cause any problems.
Generally upgrading the RAM would not void most warranties but I can't guarantee that with your system. You can see all the compatible upgrades for this system HERE
