Hi folks not a complete linux noob here somewhere between noob and novice. I have accquired quite a few Dell Optiplex 330 Machines 2 gigs of ram. I'm looking to install LXLE 16.04.2 64-bit on these machines. The machine I'm actually writing this from has it installed already and it's running pretty well but there are a few things I'm running into.

First of all the lockscreen. Although, I've figured it out I would like to use a lockscreen that is a little more traditional with a prompt showing the username and asking for the password. I'd also like to install some type of more traditonal screensaver. Any help pointing me in this direction would be greatly apprecitated.

Seamonkey, while the browser is fine for certain applications I find that I am unable to watch netflix or amazon prime video on these machines through seamonkey. Though Firefox seems to work. I would like to use seamonkey as my main browser but if it's not possible to use netflix or amazon prime I will have to ditch it for firefox :(

Basically my plan for these machines aside from a few for personal use is to get them setup as very basic desktop pcs for word processing, web browsing, etc and possibly donating them to a church or youth center. I'd like to make them as user friendly as possible for folks to use. So my last question is that after I have removed the applications I don't believe to be neccessary or ones that I prefer over the base install (VLC over Parole) etc can I use Bodhibuilder to install that base onto the other machines? Basically maxing my own remix of LXLE? Will it retain the menu positions, software, etc?
