Daisy-chaining routers for separate networks?

Hi everyone, first off - please excuse my ignorance about networking! Hopefully you can be of some help though.

Here's my network setup and use case:

I have 2 wireless routers, and want to set things up in this way:

3+ laptops get internet access (wirelessly).
2 desktops get internet access (wired, same internet "source").
The laptops should be able to share folders (some are macs, some run XP) between each other.
Anything shared on one of the desktops CANNOT be accessible by the laptops.
Ideally, the desktops would have access to stuff that's shared on a laptop, but this is not an absolute requirement.

I have been told that I can set things up like this:

Router A connects to cable modem via ethernet cable.
Router B connects to router A via ethernet cable (I hope I have the terminology correct - the "uplink" (or maybe WAN?) port on Router B, connected to a LAN port on Router A).
2 wired PCs connect to Router B via ethernet cable (to its LAN ports).
3 laptops get wireless connection from Router A.

Is this correct?

I have tried this, but I cannot get any internet connection to the wired PCs. I have tried turning DHCP off, and messing with the IP address of Router B, but to no avail.

I have also tried to use LAN ports on both Router A and Router B when connecting the two (i.e. the Router B uplink port is unused). In this case, the desktop PCs have an internet connection, but the laptops can still see shared folders on the PC.

Is there any advice you can give? From searching around, it seems it can be done - but the settings on the routers are complicated. I am hoping someone could give a quick overview of the settings (IP addresses, subnet mask, DHCP, etc.) and then if I still have trouble, I can ask specific questions about the settings, because everything is so confusing to me!

Thanks in advance!

PS - I think that I can use a simpler piece of hardware (a hub? switch?) in place of Router B, but I would prefer not to buy anything else if this is avoidable, since I already have the 2 routers.

Follow the diagram. Note the usage of a crossover cable. Most likely you used a patch which won't work.

Use the windows firewall on the pc to block access to the laptops. This will give you the share security you want.
