Click the link Bruce (photobackpacker) gave you and follow the instructions (or use the similar one on the Ilfordphoto site). It will tell you 100% if it is your safelight or not: no need for all this speculation. I do this every time I use a new paper - it takes 20 minutes.

As long as you do not keep chemicals such as the smelly type of sepia toner whose fumes can (in theory at least) fog film and paper I can't see any reason not to keep paper in the darkroom. I keep most of mine in a spare fridge with my film in my kitchen but leave some (the larger sheets) in the darkroom without any problems.

Good luck, Bob.
