Sure - you can adjust the MTU if you take the modem out of PPPoE mode and use it as a bridge with a software PPPoE client or a router. The only clients that Earthlink supports are Winpoet and the builtin WinXP PPPoE.
I have Earthlink DSL with Win2000, and I have my modem in bridge mode and am using RASPPPoE for a client, hooked into the DUN. Every time I have to call for support (not often, thank god) it gets ugly, especially now that their support is offshore.
1500 MTU's only work well with cable - PPPoE DSL should generally be 1472, except AOL needs 1400.
If you don't have a phone jack anywhere near the computer, yes, you can run them all wireless, but you should do the router config with a wire. Maybe the easiest way would be to use one of the laptops if it has a builtin NIC. Once configured, you can switch it over to all wireless. Just bear in mind that you *may* have to reconnect the wire to take care of any issues in the future - like if the wireless stops working or you need to upgrade the router's firmware.
