Help with Switch BRANDS and a setup.

Hey all,
In an effort to speed up and cause less problems in my current network, i'm looking at the following Unmanaged Switches:
1. TRENDnet - TEG-S80TXE

2. Netgear - GS608

3. Linkskey LKS-SG8P
http://www.tigerdirect.com/applications/SearchTools/ite...

I can't seem to find any decent reviews about any of these... which is why i'm here.

Which would be the best to worst?


Also, here is how it will be setup



and (if i can get another question in) is this the best WiFi router for my situarion, it is only for customer use but I don't want them to be able to get into my Wired Network.

Thanks all!
B
