The larger the objective lens diameter, the more light that can enter the scope giving you a brighter image. The 50mm objective lens will produce a brighter image then the 40mm one. The 40mm might hinder your low light shooting where as the 50mm will help. The 50mm lens will also give you slightly more field-of-view.
I personally don't think a 50mm is needed. If it's too dark, I don't shoot. The 40mm will mount lower and catch on less brush. Go to a store that sells those scopes (or any scope for that matter), and look through two scopes of the same brand and model with a 40mm and 50mm lens. Compare the brightness that the two different size lenses produce. See for yourself if a 50mm objective lens is worth the extra $ to you.
This has an example of two images as seen through two different objective lens sizes:

Like Old Fuzz said, getting some Burris rings and a Burris base won't be a bad idea. If not Burris, get Leupold. Just make sure you match the rings with the scope tube diameter. I recommend 1-piece steel bases. They less pieces you can get away with the less chances of having a problem with accuracy. Tighten the base screws into the rifle's receiver with some medium strength Loctite Threadlocker.

I agree with what renderman and Turk have said, but I would like to add a few things to ponder. First of all a rifle is a long term investment and the scope is an integral part of the outfit. Consequently I would put as much as I could possibly afford into my scope. If you don't today you might regret it later. You've invested in a nice gun, so make a similar investment in the scope. Personally I would buy a Leupold, but that's all a matter of personal preference. Secondly, I don't know how you'll be using your rifle, but do you really need a variable scope ? If you'll be hunting varmints at over 100 yards, you'll probably be keeping it on 9 power. Most experts agree that most people buy variable scopes not out of necessity and would be better off with a fixed power scope depending on their needs of course. As far as the rings and bases and I hate to sound like the Leupold spokesperson, but I would buy Leupold bases and rings as well. I think the medium rings are sufficient, but the shop owner could tell you exactly. The additional money you're going to spend is peanuts in comparison to the money you've already invested. I know sometimes it's difficult to spend the extra money for the scope and accessories, but I think you'll be glad you did in the long run.
Just my 2 cents. Good luck and happy hunting !!!!
By the way, check out the link one of the other guys posted. There's a lot good information there.

The only advantage to the 50mm objective lens is letting more light in. To find the exit pupil you divide the ob. lens by the power. For example, at 9X the exit pupil would be 4.44mm (40 divided by 9)and at 3X it would be 13.33. Your eye can only handle about 3.5mm so any extra light is wasted anyway. If you got into a higher magnification the bigger objective lens would come in handy. As for bases and rings, buy a steel base and steel rings that are adjustable. You can make major moves with the rings and fine tune the sighting in with the turrets on the scope. Millet, Leupold, Redfield and Burris all make good quality bases and rings. Make sure you use Lok-tite on the screws so they stay tight. Congratulations on the new gun and have fun shooting.

It depends on what you are hunting, and with what round. But I usually go for the 40. With a 50 you have to buy taller rings, and when you have to set your scope up higher, you lose a little accuracy. I would use steel mounts and rings.
If you buy your scope,rings and rifle from the same store, most of them will install the scope for free, and bore sight it.

That gun will probably shoot as good as any scope that you buy can see. You will not be wasting money with the bigger better scope. If you are going to shoot at close range most of the time, then the 3-9 scope will be adequate.

You're buying a Burris scope, might as well buy the Burris rings and mounts. They are all designed to work together.

If you get the x50 then when you are scouting in the spring, and when you find just the best spot that has a long shooting lane, you can feel more comfortable making a long shot where as you get the x40 and you might be a little bit hesitant that wether or not you have a nice clean shot. In Hunter Saftey I was taught that you can only take a shot only if its a nice, clean shot.

The 50 will give you a closer view, but you will have to use high mounts. The lower the mount to the bore, the more accurate the impact point.
