HELP!! connecting 2811 router to cable modem

I recently got a cisco 2811 isr and i want to connect it to my cable modem and have spent a week scouring google and forums looking for a solution with no avail. Any assistance would be great!

Here is the hardware layout

arris sb6141, comcast cable isp

cisco 2811 isr

rosewill 16 port un managed  fast ethernet switch

cisco air-lap 1252 ap

no i have the config to a point to where it pulls a dhcp address from modem but i still cant access the internet plugging in from fa 0/1 to laptop as well i need to configure the ap as autonomous ap i would like the topography to go like this

sb6141>>>>2811>>>>switch>>> ap/ hardwired pc's/server

As i am new to cisco i feel really dumb not being able to get this im sure its a simple mis-configuration

heres the output of   sh run
