All depends on

1 how much you are willing to spend. wireless tends to cost more bcos of the equipment. wired doesnt cost so much even if cabling is involved.
2 which parts of the house are you gonna be when you want to connect to the network. if not that many places then wiring up wouldnt be a problem. if you need access at lots of places eg toilet...LOL then you might need wireless
3 do you mind running cables around the house. the wife/mother might mind. also back to Q1
4 how particular are you about security. with wired, someone has to phsically tap into your network thru somewhere there are cables running. with wireless they can wardrive and might be able to get into the network
5 your house itself...some homes have problems with reception at certain areas. this can be solved by adding more APs..but then we come back to Q1. also there is a problem with interference with wireless.

I hope this helps make your decision easier. As for which standard to use if u decide to get wireless. u can make up ur mind later once you decided on wireless or wired. If you can I recommend trying out wireless by borrowing it from a friend or some stores will loan a set to you to test.
