I did this for my c35, so it should be similar.
If you don't feel comfortable doing this, don't do it. I don't take responsibility for any injury or damage.
First you'll have to get the right sockets, i don't remember the size, but the bolts should be tamper safe torx bolts.
When you're ready to start, disconnect your battery and the airbag fuse (just to be safe) and then wait about 20minutes so everything can be discharged.
Now you can begin taking the airbags out.
On the driver's side, there should be two cover pieces on each side of the steering wheel that you should be able to pop off with a screw driver. You'll see the bolts when the covers are popped off. After the bolts are out, the airbag and cover should just slide off.
For the passenger side, you might have to take your glove box out, I had to. Mine was above my glovebox, so I had to take it out completely.
I had an igniter under my center console also, so you might want to check for that.
When it's all out, you'll probably want to take the SRS light out of the gauge cluster since it can get annoying.
Also, if you plan on storing the units, have them face up. That way if they do go off, they don't shoot through your roof.
If you google this subject, you should be able to get a walkthrough with pictures and the socket sizes.
