I currently am using a ASA 5510 Firewall and ASA 5516-X, by defaut what security settings aren't enabled that I should have enabled in any network configuration? Also, by Default is IPS/IDS enabled or is this something that needs to be configured? Any advice would be appreciated and any recommendations as well.

few i have a choice between 5510 and 5516 I would stick with 5516 as it has firepower features. you need to get a lic in place in order to use the firepower services it come with 1 year, 3 year and 5 years.
now coming to your question what security setting you need enable it depends on your setup. you want legacy layer 4 security in that case 5510 and 5516 both can do the same for you. but firepower runs only 0n 55xx-X series models.

Yes, I do currently have a lic for the 5516-X. Are all features by default active do is this something you manually have to accomplish? We are going very simple here, On one port of the firewall, we have a guest-WiFi then on another port you are looking at the main WiFi along with the LAN network, and another port going to a different switch is the Voice. They're al segmented, with that being said. What is recommended for that type of setup? Generally speaking that is.

first think first if you are concern about security element of your network and want to use layer 7 inspection. login into 5516-x and give a command
"show module sfr" if you have a sfr install on the unit.
are you asking for a best practice configuration for this setup?
do you want me to write a basic script?

I won't forget.
Yes a basic configuration would be nice for the best security practices, right now I don't have any bad habits when it comes to configuring things so if someone could show me the right way from the beginning it would be appreciated.

do you have a topology diagram and ip addresses?
if you can forward it this would be helpful to understand and write a basic config.
