I heard from some people that TSL on Steam has more modding limitations than it's disc counterpart (Can't install too many mods without problems). I typically have around 2+GB of mods and I make my own patches to make all of these mods compatible. Is it true about the limitations or are there none?
The limitations refer to using the Workshop. Avoid doing that and just stick with typical modding and you'll be fine. The Workshop implementation is ass anyway, it will just lead to headaches for anything more than simple overrides like textures and so forth.
Yes, just use the Steam install directory as you would for the GOG or CD version. TSLPatcher won't handle automatic lookup because of different registry entries, but you can manually point it to the right location.
