You speak of architecture, landscape, and museums... all wide subjects. I would start with the 35L - it's the lens I keep on my 5D. It's also great for children. You don't really have a lower priced option - the non L 35 is pretty clunky.
Next, for your daughter, an 85 is great for portraits... I currently own both the 1.2 ($1850) and the 1.8 ($380). Both are FANTASTIC, but honestly the 1.8 does almost everything the 1.2 does, one stop slower. The 1.8 is a really high value lens (but I love my 1.2). My advice is to get the 1.8, and upgrade to the 1.2 later if you really like the focal length.
I also owned the 50 1.4 and the 50 1.2. I think they're both great lenses, but I couldn't justify the price difference between the two so I returned the 1.2. The 1.2 produces slightly better images, but I felt the big difference was build quality - If money were no object, go with the 1.2. But since you specified a budget and the 1.4 is a very good option, I recommend the 1.4.
The 135 is my street photography lens - I personally like it's ability to discretely capture portraits... but that's wasn't on your shot list, so I'd throw in a 17-40 f/4 L ... it's great for building interiors and museums - you can step in front of everyone and get shots without people. It's not the fastest glass... but it's wonderfully sharp.
So, my advice would be:
35 1.4 L
17-40 4 L
And that should be about $2800-$2900 by the time you add your filters. Throw in a high quality Polarizer for your primes, and you're at $3000 and fully kitted.
