Hmm. I have a mix of things purchased from LBS, Amazon, and Nashbar.

Spare tubes are a mix of Kenda, Bontrager, Giant and Specialized, all purchased at LBS.
Frame pump is a Topeak Road Morph G. Highly recommended as it has never let me down and pumps up to 100 psi with moderate effort
Floor pump is Bontrager, purchased by my wife about 4 or 5 years ago at a LBS after the cheapie we bought at Target failed. It works well enough though I did have to replace a $1 part last year. Not a big deal though.
Tire levers are cheap. I bought mine at the LBS but you can get those anywhere.
I have several multi tools. The one I like best is a Nashbar brand.
Rack. I believe it is a Saris, purchased locally.
Water bottles. A mix of locally purchased and purchased over the Internet.
Glasses. I bought a set of photo-chromatic glasses from Nashbar for $20 on sale.
Helmets. Look for sales. My current favorite helmet, a Cannondale road helmet was purchased locally. My wife's was an Amazon purchase.
Clothing is mostly purchased locally. I have purchased a few jerseys, shorts, and shoes online and have regretted it.
