Glad you like it here, everyone grows to eventually 
I think A_S might have meant the models on that site that are just general clutter, such as the drink cans, letters, books, and so on.
As for modelling packages, there are a couple of free options. With HL2 around the corner, and like most new FPS's, it's use of more 3D modelling package generated scenery (or "props" as they are called in HL2), it might be wise to get learning some modelling skills too. The most widely used free package is milkshape, which is actually shareware but will last 30 days or so for free (and its been known to last longer if you know what I mean
). If you like it and plan on using it, its $20 or so to buy it, so it won't break the bank if you deside to support them. The other is Softimage XSi, which has just had a free version released for putting out HL2 content. I've no idea if it supports HL1 files however. Do google searches on them to find out more I guess, or just search these forums.
