in wads, texture sizes dictate two things.
firstly: you get one lightmap sample per 16 texture pixels. a 64*64 texture will thus have 4*4 lightmap samples (actually, (4+1)*(4+1), but hey).
secondly: the sizes define the default repeat tesselation of any replacement textures.
Thus, if you make your wad images too big, you will generally have to make your tga images huge, as each one will have to cover more wall.
Personally I wouldn't make a wad texture larger than 256*256.
Floor texture sizes very much depends upon your intended content, and how much its meant to appear to repeat.
Bear in mind that I'm neither a mapper nor artist, so take my words with a pinch of salt.
