Counter Strike Source in GMOD Help!!

Is there a download that shows all the counter strike source spawns/items. I do not own CS:S but I get alot of ERROR messages when I play RP servers. Is there any way to fix that by downloading any counter strike items?

Unfortunately the only way to (legally)obtain the needed models and materials is by purchasing CSS.

And the free way (legally) to obtain the models and some materials is by using hldsupdatetool

CS:S is fun, just buy it.
