I agree with Eero, VLANs are real security.  It will require time and 
effort and maybe some additional equipment.  If it helps you sleep at night, 
it's worth it.  You might start with just IP groupings and rules though.

I have an admin network that only has a couple of computers wired into it.  
admin has access to my home and the internet.  My home network (mostly 
wireless, satellite box, etc) does not have access to admin, but does have 
access to the internet.
That's VLANs.

I also recommend floating address dhcp for addresses .100-.199 and dhcp 
reservations for .200+ devices that should not have access to the internet, 
like a printer.  And addresses below .100 for devices you know and wish to 
identify regularly.  Then you can try limiting access to the internet to none 
for .200+, only to ports 80, 443 for .100-.199, and full internet (but not 
admin) access for your iphone, xbox, whatever.  It's not as strong a separation 
between trusted and untrusted networks as VLANs are, but it does inhibit some 
multi-stage infection vectors.  I do both.

I can still use my iphone as a remote for my satellite box with this config.  I 
don't fear having my set top box infect my computer that I use for web-banking 
because they do not talk.

D-Link has some low cost vlan-smart switches available that seem to work pretty 
well at a totally acceptable cost.

Ethernet over powerline is an easy way to get more private devices off of your 
wireless network without running cat-6 through your walls or punching your own 
RJ-45 connectors.

PFSense should be able to provide you with separated networks with additional 
ports or by send multiple tagged VLANs to a smart/managed switched where you 
can break them out as needed.  And statically assigning addresses, blocking 
communication by address range, it's all in there.

        Good luck,
