Light and Life does publish their own stuff, as well as carry books from just about every other Orthodox publisher out there. Their catalogues are wonderful. You could spend hours going through one of them. They have a website, but have them put you on their mailing list so you get their catalogue. It's free. The website does not have everything on it. Light and Life also carries some jewelry, icons and other things in their catalogue. However, it would be cheaper getting those things directly from the sources, such as Festal Creations and Holy Transfiguration Monastery.
You are wise to stay away from Monastery Icons. We dealt with them briefly and it was not a good experience. Holy Transfiguration Monastery, near Boston, has a wide variety of icons, as well as brass incense holders for a low price. You have to pay a fee for the catalogue (I think eight dollars,) but it is worth it.
For relatively cheap but good Orthodox costume jewelry, key chains, visor clips, night lights etc. try Festal Creations. Call (800)747-9245 for a catalogue. The catalogue will have more in it than the website. If the congregation at your church is wealthier than mine (mine is pretty poor) they may want real gold and silver Orthodox jewelry. The source for that would be Gallery Byzantium.
