T530 Software and Hardware update questions

I have a couple of quick questions for those of you in the know.

First I am wondering what a good reliable source is for the FHD screen for the T530? I have the HD+ but I am thinking of upgrading to the FHD.

Second, when I run windows update I get three optional upgrades all related to Intel and I am wondering if I should upgrade them? Here is what they are.
1. Intel Centrino Advanced N6205
2. Intel Active Management Technology - SOL.
3. Intel Management Engine Interface

One last question, there is also an update for nVidia. Should I upgrade that or wait for Lenovo.

Thanks for all the help.

 

The most reliable source is to purchase it directly from Lenovo, though it will be expensive. eBay is probably your next best option.

As far as updates, if it's running well, I say why fix it? I personally never use Windows or Lenovo update.

 

I really hate messing with WiFi drivers, since they're often rather finicky. But you could install the Intel Centrino Advanced N6205 update if you like. The other two are not worth updating, particularly if you don't use the Intel AMT software (which, unless you're in some large corporations, you won't).
