You have GOT to be kidding, right? You want to keep a glass top coffee table in your baby's room?
I wouldn't keep it there, but I am always overcautious. Accidentally you drop something on the table, it breaks the glass, glass flying, you better hope the baby is not with you then!
As for changing table, I like the drawer style ones with a detachable changing top on the top. When baby is no longer in nappies you can detache the changing top and still have your chest of drawers.

Ikea also have a wall mounted changing table, that flips up when not in use where you still can store your changing accessories such as wipes and creams and nappies on the inside.

I had a Mamas & Papas Unit with bath:

When baby started sitting up and there was a risk of him falling off (at six months) I had a simple changing mat on the floor wich I stored under his cot.
But, get rid of that coffee table.....
It doesnt matter HOW sturdy the glass is, faced with a kicking little baby you can soon have a disaster on your hands. I shiver when thinking og glass penetrating soft new baby skin, and worse baby's little organs.
