Starting from the 1st pic my recommendations are:
Gouden Carolus Carolus Dor - Gouden Carolus anything are generally good belgian beers
2nd pic:
Samuel Smiths' Pale Ale, Try to find the Oatmeal Stout too
Looks like I see Young's Double Chocolate stout, grab that yummy bottle!
Unfamiliar with West Coast, but I've heard people say ok things about them
3rd pic:
now we're getting to the goodies. The Chambly Noire is a nice dark beer, the Blanche De Chambly is like a light version of it. Unibroue makes good beers in general as well. You are safe with any choice that is fresh. That La Fin Du Monde is a treat!
I see Westmalle Double and Tripel, get both. Great Trappist Belgian Beers. I am a huge fan of Trappist Belgian Beers. I urge you to sample all that you can find. If you drink the westmalles back to back start with the tripel as it is lighter than the double. Always drink your beers from lightest to darkest so you get the best chance for tasting all the flavor complexities. I also spy the Youngs Double Chocolate Stout on the shelf just below the westmalles... The Fischer/Fuller's are alright english beers. London Pride is an easy grab for me when I'm in the mood.
4th pic:
See that Arrogant Bastard Ale? Buy 2 and send me one. I absolutely LOVE those ales, but I can't get them at my local store. I'm serious... I will pay for them of course!
The Hobgoblin Dark English Ale is great if you like your dark ales. The Belhaven St. Andrews Ale is tasty too although I don't typically go out of my way for it.
Now we're getting to the hefe weizens!
The Franziskaner is a good commercial example of a hefeweizen. You'll notice a bit of sulfury odors/flavors and maybe some bubblegum but it should be muted.. these are normal and desired. HefeWeizens are good summer beers. The Spaten Dunkel is alright.. if you can look for Warsteiner's Dunkel, it seems to be just about the right balance I like in a dunkel. Dunkels are like german brown ales only nuttier.. Think of a newcastle, but nuttier and a little darker roast.

Samuel Smith's IPA - great beer. Hands down.
Aecht Schlenferla Rauchbier - Top shelf, farthest to the right on the pic.. This beer will put all the hair on your balls you'll ever need. I HIGHLY recommend getting a really great sharp cheddar cheese to eat along while you drink this beer. It's made by smoking the malt. You will taste smoke in the beer and at first it is very odd, by the end of the bottle though, you'll wish you bought two. This is not your casual beer drinker's beer, this beer will test your desire to learn what real good beer is. Great beer, turns almost everyone away at the first sip - Buy two bottles, if you make it to the end of the first one, you'll want another. Does take some getting used to.. ok disclaimer over.
Kostriker is a Shwartzbier.. think of it like a black lager. This is possibly my favorite dark lager german beer ever. A good buy no matter what.
The last pic is hard to make out by the label but I do see the Urthel. Now these Urthel beers take a bit of getting use to for me, but that Bock is pretty damn good.
Seems like they have a pretty good selection. It was hard to pic out some of them by the label design alone based on the pics, but I hope I got you on a good start...
EDIT:
I guess it helps if I explain dark and light beers a bit... When someone says dark beers it's because a few types of grains have been used from roasted to burnt malts... If a beer is classified as dark you can expect to taste roasted/toasted/coffee/toffee/and deep caramel flavors to be in there to varying degrees... lighter beers are made with simpler grains that for the most part have been left alone with exception to caramel malts which give the beer a bit of a sweet taste and generally use lighter malts. Lighter beers are generally lighter on the stomach, the darker the beer gets it generally means it will have more mouthfeel and be more filling, but that is not always the case, just a general guideline so don't apply that concept to everything you come across... A good example of this is say Young's Double Chocolate Stout .. it's thick, chocolately, and sits in your belly.. then switch over to a black lager like say that Kostriker.. it's got the roasty flavors but it's not nearly as heavy as the double chocolate stout, but the color is the same.
Anyways.. I'm sure that was more confusing than helpful, but I wanted to try to help explain the flavor difference between dark and light beers as simple as possible...
