Also note that if you pickup the add ons for GTA IV then you get to download the game twice(sure connections are fast these days but an extra 16GB really?). It doesn't integrate with GTA IV. So if you load up GTA IV and click on the expansion pack it takes you to a screen to buy it and vice versa.

Yes, you don't get the two episodes as DLC over Steam, you get the standalone SKU "Episodes from Liberty City". Just the same as if you bought the EfLC retail box on PC.
