need help configuring cisco 881w for home use

I just want to say, i will be trying this out.  i just got a 881w off of ebay.  ill be using it for fun, and for a home router solution.

isp(comcast)--->docsis3 modem--->881w~~~>wireless bridge in the computer room--->switch--->pc's

and isp(comcast)--->docsis3 modem--->881w~~~>wireless laptops, gaming devices etc...

last night, before i found your article, i was able to console in over serial.  usb>serial is a good thing.  but cisco needs to upgrade to usb console.

first thing i did was power on the router and reset it to factory defaults.

then

en
service-module wlan-ap 0 reset default-config
service-module wlan-ap 0 reset

after that, to begin testing i connected a current connection to the FE/4 wan port

and my pc(win7ultx64) to fe/0

first, no DHCP on the 881w by default.  so second i manually set my IP to 10.10.10.4 255.255.255.248
i am not able to access or ping the router.

so i do a sh run and it tels me that all the ports are shut
so i do a no shut on fe/4 and fe/0

then on fe/4 router#(confit-if)ip address dhcp
i can then see it is assigned an ip address from my network. 192.168.0.xxx

from here, i still dont have access to the web interface.

so i have to go to router#(config) and do
ip http server
ip http secure-server
ip http authentication local

and doing line vty 0 4

transport input telnet
transport input telnet ssh


from this point i am able to access CP from the WAN address using a seperate machine on the existing network.
i can do some basic things in there like set the vlan1 ip and subnet
turn on dhcp etc.

the wireless tab lets me set the ap hostname

so i then change my machine back to DHCP while connected to fe/0 and i get an ip address in the 10.10.10.100 10.10.10.150 range which i set in CP from the other computer.

so from my machine i am able to hit the web interface from 10.10.10.1

!now this is where i get messed up!
i am not able to access the AP web interface as i need to replace the IOS


so via console i do
int wlan-ap0
ip address 10.10.10.20 255.255.255.0
and here i get a conflict saying it is in the range of vlan1 
so i set it to 10.10.20.1 255.255.255.0

service-module wlan-ap 0 session

from there i get
ap#

from this i need to TFTP back to my desk and get the new IOS loaded but i cannot ping my desk on ip 10.10.10.100  as it says it is un avaialbe

so i do a ctrl^6 x disconnect

and at router# i can ping 10.10.10.100 succesfully

so that is where i am at.

also, not as important as i will figure it out once i get gui access to the ap.
i cannot get to the outside world from my dektop--->switch--->wireless bridge~~~>881w--->modem--->isp
i assume that is because i do not have NAT setup but i dont know.

any help would be greatly appreciated.

i was refering to this Link at the beginning of my question.

my main thing i am aiming to do is replace my existing dlink router/ap combo

i used to have a cisco 806 but i lost it when we moved.  it had DHCP on by default etc... and was able to access the web interface out of box.
