Linksys WRT54GS Access Restriction Policies

I am finding it challenging to correctly define Internet Access Restriction
policies on my Linksys WRT54GSv4 wireless router. Documentation does not
describe multiple policies being enabled. I think that multiple policies
should be from most restrictive to least, but I am not sure.

I wish to deny Internet access from my child's WII and PSP from 10:30 PM to
6:30 AM. Also, I want to filter all hosts for blocked words and blocked
sites.

Currently, I have three policies:

1) Child_Evening --
WII and PSP MAC Filter
10:30 PM to 11:55 PM
Deny

2) Child_Night --
WII and PSP MAC Filter
12:00 AM to 6:30 AM
Deny

3) SiteWord --
IP Range 192.168.1.2 - 254
Block Various Sites
Block Various Words

I would like input as to the correct use of multiple Internet Access
Restriction policies
