I would STRONGLY recommend you DO NOT just use the content because the creator is listed here, unless the marketplace add or website specifically stipulates that you are granted extended license with your purchase. Best practice is to contact a creator, explain what you are doing and more often than not, they will be happy to come to an agreement with you. RECORD YOUR AGREEMENT in some way shape or form. If you get it via SL marketplace purchase, LEAVE A REVIEW and mention that you will use it on another grid with the agreement of the owner, and try to deal with larger creators with a good reputation.
Textures
http://www.texturesrus.net - Huge resource of textures for all needs. Purchasing via the website grants you license to use the textures in all virtual worlds and to even use them in your commercial projects.
http://www.studio-skye.com/ - Another great place for textures. A bit pricey, but the quality cant be beat. Same deal as above with regard to the license.
