Center stock has turned brown and looks dead. What do I do? A new shoot is starting from the side and seems to be from the root. Lisa
It sounds like your plant has just completed it's blooming cycle.
The flower will fade after several weeks or longer.
Though this plant is a one time bloomer they are not done yet!
At the base of the dying plant you will find a 'pup'.
Carefully cut away the dying mother plant to allow more light to get to the replacement pup.
Your new plant will eventually fill the pot and with the right care and light conditions the new plant will flower.

When I purchased my Bromeliad it has a beautiful raspberry red color. Now it's turning a light brown. It's indoors in a potted planter. Why has it turned brown?
Most likely your plant is just aging and it is nearing it's life cycle.
Here is an article with more information.

I am interested in buying bromeliad bulbs so I can try growing them myself. If you can help, I would appreciate it.
Inquire at local garden centers or greenhouses.
Do a Google search for suppliers that can ship to you.
Ebay is also a good source for plants that may not be found locally.

My flower is dead, but the leaves are green. Should I cut the flower off? It looks ugly.
Yes, you can remove the flower, though your plant is not nearing it's end.
If the plant produced a 'pup', you can remove this and repot.

Are the plants dangerous for cats?
Bromeliads are considered non-toxic to cats. However, many cats will vomit after eating plant material, even from a non-toxic plant. Many bromeliads do have leaves with sharp edges which could potentially injure a cat.
When several pups have grown together and are over 3 years old, can they be separated and replanted?
It actually is better to wait to separate until the pups are at least 1/3 the size the mother plant. Small pups don't divide well, but larger pups almost always survive.
You should make the divisions while the plants are actively growing, generally a warm part of the year.
After separating the pups leave them to sit on the counter for 24 hours before repotting. You can dust the roots with a fungicide.
Use a potting mix suitable for Bromeliads or an Orchid medium.

I have a bromeliad that has been in a pot for several years. My guess is that it is several pups. I think it was blooming when I got it and never bloomed again. Any chance I can resurrect a blooming plant? It looks green and healthy.
The part of the plant(s) that are still green should be capable of blooming. These articles will help you:
