I haven't made tf2 maps before but i've made css maps, but I want to get into it, is there any special textures and such that are good besides the defaults?
Everything you need is in there when you load the SDK into the TF2 "mode". All the textures. However, you can use the keyword "tf" to search for just tf2 textures.
Besides the swamp and construction packs, not to my knowledge, but just make sure you use only tf2 textures in a tf2 map, they don't blend well with hl2 textures like CSS might.
