Amber, I agree with Lin's good advice but in addition I also think you should mist your brom with a spray bottle instead of watering the soil.
Bromeliads are epiphytes and gather most of their nutrients and moisture from the air. Their roots mainly just serve to hold the plant upright so it can collect stuff effectively. So, strange though it may sound, those brown leaves might be because you weren't watering the leaves. In nature, they grow in places with high humidity, attached to dead tree branches on the ground and also on living tree branches, so they collect dirt and stuff that falls from the trees as fertilizer. Mine are all out in the garden under the oak trees, but I do occasionally walk by them with the orchid fertilizer sprayer, and give them a spray.
When it comes to separating the pups from mama, you will know when to do it, and it's not difficult. Mama will look more and more raggedy but she will keep feeding the pups, and making more for a while yet. Some people cut them off but I've always been able to just pull them apart from the mother plant. Don't worry if there are few or no roots. Just set the pups on some loos soil, and keep them misted.
