I use the higher end Metal Netgear Routers and switches for myself.
I've put in the consumer grade Netgear routers for friends.
All working well.
Do you have cable or DSL?
In general cable is a cinch to set up.
DSL can be tougher, you need good documentation about your modem.
With DSL, you need to make changes to your DSL modem AND the router.
With cable, if you have the cable modem working on one machine already... your home free. The router setup is very straight forward to work with the cable modem.
If you have DSL, I would recommend buying the router from your DSL provider, making sure they support setup. You'll pay a little more buying through your DSL provider... BUT, in the end it will be worth it.
I'm far from the common level user, but I've pulled my hair out with different DSL modems and bad documentation and different DSL providers.
Back to basic recommendations...
If your house is already wired, and you have more than 4 items...
I would spend the money on this...

I have an old trick now documented on Netgear.
Click here
You can buy one of the 4 port Netgear wireless routers on sale for 20 - 30 bucks, and turn it into a WAP only, plug it into the above router. Now if you ever want to upgrade/change your wireless, you don't have to chuck a perfectly great router. Plus you can use the 4 ports on the router turned WAP, just as you would the other ports on the 8 port router.
I know for a fact, the older metal netgear stuff and the internal network cards from Netgear are /where made better than Linksys stuff. I had been in both.
I haven't opened the consumer/plastic Netgear, so I don't know.
I should, I now have a spare hanging around of a 4port wireless B router.
The Linksys's I've worked on have been fine, easy to use and install. The folks I know that just bought them , read the directions and installed them, did well with them.
I've never used D-Link, but not liked what I've read about them.
Not used Belkin, haven't read anything real about them. So I have no formed opinion on them.
For the wireless router and wireless cards.....
If your going for standard B or G, you can intermingle brands.
But as stated above, if you need to call tech support, it will make life easier, so they don't just blame the other brand. I just don't need or use tech support.
I use B at home and for work, for web browsing and email, you'll never notice the difference.
But for moving files you will see the speed increase MIMO over - Super G over - G over - B. As long as your signal is strong, at medium distances.
Believe it or not in most tests it has show too close hurts speed. MIMO has shown to increase range and reduce dead spots.
But if your going for Super G or MIMO, you MUST buy all the same brand of Super G and stick with it or you wont get the possible BW/speed.
Also, use wired as much as you can.
For the most part the single wireless access point is only as fast as the slowest connection into it. As you, I use it only for my laptop when working on the living room. But when in my home office I have a CAT5E/RJ45 hanging there for the laptop, so I get the speed of the hardwire when I have to move files.
And PLEASE . . at a min locked down your WAP via MAC address permission.
And change the default password for the admin access to your router.
