Paradigm Technology Maxnet router upgrade?

I have the standard Paradigm Technology router that Maxnet gives out with 4 ports on the Premium plan (midway between Indy and Biz) and I am wondering:

1) Is a hardware firewall built in?

2) If I buy my own router modem will I get better performance?

3) Is it easy to install if I get a new one?

4) Suggestions on make and model? I would like a firewall built in. (I already have antivirus and firewall software- ESET's security suite with Nod32)

Thank you!
