Yes the bowling alley will go with it. And no as you need the alley to make it work. If you try to download a venue from the exchange that has the bowling lanes in it and you don't have the EP required to make it work, then you would end up with a building without the bowling lanes as the game will replace any missing items with default items from either the base game or any EP's/SP's that you do have installed.
Yeah - this is the shortcoming to uninstalling Expansion Packs - you can't use the build/buy or CAS assets without them. And University Life has a ton of good content, too. Even if I don't plan on taking a Sim to University, I would be hard pressed to do without this particular XP. Just too much great stuff that I would miss.
