Trying to optimize a home network with ABS, AE and a router! New advice!

Question

I currently have this setup:
Cable modem going into a linksys router.
1 line goes to an imac
1 line goes to an emac
1 line goes to a silly windows pc
1 line goes to an AIRPORT BASE STATION (usb -older one)
From the ABS - I power 2 laptops (ibooks) - wirelessly
Also in the network is 2 Airport Express - 1 in an upstairrs office with itunes and printer and the other one downstairs in the entertainment center for itunes.
I do not get great range but it is workable upstairs and down.
If I remove the ABS and just use the 2 AE, will I get a bigger, stronger wireless network? I do get itunes drop out downstairs sometimes. Does the ABS do anything for me in this setup? I added the AE for itunes and printing but was told that it would be better to remove the ABS and just use these devices. The older ABS does not extend the netowork, correct?
If so, should i plug directly into the AE from the modem and then go to the router? What do I gain with the current setup vs plugging into the linksys router AFTER the AE?
Any advice would be helpful

You will find that not all 3rd party routers will allow you to extend the network and use WDS, as shown in th link.

Basicly it is a confiquration issue after that, You don't need to use 2 routers like you have now.
Most users make the mistake and try to use a setup like you have and both routers are setup assign IP's, only the main can be confiqured this way.
This is one of the many reasons why it is a good idea to use all Airport Equipment to avoid incompatibility with 3rd party equipment. Some will mix and match some will not.
Hope this helps.
