Those are probably the two most common questions we have around here. That being said, Wayne is absolutely right in the fact that they are very subjective. Most people swear by ernie-balls and they are very good strings to start with. As Wayne says, 9's will be a good start and are probably what you have on right now if they're stock. Once you get some more playing experience under you, you'll want to start experimenting with different sets and sizes. None of my guitars use the same set of strings because they all have their own sound and react differently. I'll admit, NONE of them are Ernie Ball's.
As far as picks go, I suggest medium to heavy for picking (as apposed to chord strumming). The Dunlop Jazz series are great for all around and will work for strumming too if you just lighten up your touch. I use the Jazz II right now. My suggestions there is to just go to the local shop and get a dozen or so different picks then try them all out to see what works best for you. Keep them around as you start getting better and try them all again. Most of the ones I first bought never got used again. The funny part is, when I first started I hated these Jazz picks too, until I realized how much faster and accurately I can play with them.
