Need to set up a small wireless network

[BRUINSrock]

Need to set up a wireless network...

4 ppl sharing a Comcast Cable Connection... (approx 3.0 mbps)

Combining Notebooks and PCs.. so I need to know what would be good and affordable... need wireless router, cards, and pci adapters...

I'm guessing I just need to match brands and type for example...

Could I buy??????????????????:
LINKSYS Wireless G Cable/DSL Router, Model WRT54GS w/ Speed Booster (http://www.newegg.com/app/ViewProductDesc.asp?description=33-124-136&depa=0)

and that would be compatible with...?

LINKSYS Wireless-G PCI Ethernet Adapter w/ Speed Boost, Model WMP54GS (http://www.newegg.com/app/ViewProductDesc.asp?description=33-124-139&depa=0)

and...

LINKSYS Wireless-G PCMCIA Ethernet Adapter w/ Speed Booster, Model WPC54GS (http://www.newegg.com/app/ViewProductDesc.asp?description=33-124-138&depa=0)

???

Is that all i would need? and is that the best for the money? (all had at least 4 stars from consumers)

The products are all the same as we have here in the UK, and are excellent. The only other I would say is comparable, but am unaware of the price in the US, is the Netgear products.

That is all you would need so all should be good to go :)
