What camera do I need for high-quality photos for my blog?

Hi there. I'm looking for a new digital camera. I'm a blogger ( keatonthefoodie.blogspot.com). I blog about recipes, homemade body products, cleaning products, crafts, etc, and of course take pictures of my creations. The only problem is I can't seem to take the bright, vibrant, clear pictures like other bloggers. If you go to pinterest.com or etsy.com, you'll see what I mean. The pictures are beautiful, crisp and look so professional. I have a Pentax X70 and a Nikon D70, have played around with lighting and such and just can't get the pictures I need to take my blog to the next level. I'm looking for a new camera anyways, so I would love some suggestions for a camera that can take the high-quality pictures like other bloggers have. Any ideas? If you're a blogger, what sort of camera do you use? (I'd love to see your blog and pictures too!)
Added (1). The D70 does take good pictures, but I'm not totally comfortable with it.It's too bulky for me, and It's actually my moms, which I'm borrowing, so I haven't had (or have) much time to get too familiar with it. Plus, it rarely works properly, with all kinds of error messages, so I'm planning on getting a new one asap.

Buying a new camera- help?

I'm looking into buying a nice somewhat-beginner DSLR camera. I've taken a handful of photography classes so I know fairly well how to use cameras and some of the technical stuff. I've been looking at the Canon EOS Rebel T3i, Nikon D3100, and the Canon T4i. If you have or have tried some of these cameras out, which would you suggest?

Any ideas for what to put on my Christmas list?

I'm bored so I'm making my Christmas list. I can't think of what to put on it. I love photography. I have a Nikon D5100 camera already and an old polaroid camera from the 70s. I have the iPhone 5 so I don't need a new phone. I love makeup (any good products sold at sephora?) and definitely clothing from Pacsun mainly. I like the California kind of look so any stores you know of like that would help.So any other ideas? Thanks(:

How useful is this lens?

I am interested in buying a Nikon D5100. The Nikon D5100 is normally $580, but for $760 you also get a "Af-S Dx Vr 55-200mm F/4-5.6g" lens with it. How useful is this lens? For $580 you get the standard 18-55mm lens.Is there really such a difference between these two lenses that it is worth spending nearly 200 dollars more to get the second one?
For information, I am a beginner photographer but am learning and becoming more and more experienced. I like taking a variety of photos; outdoors, portraits, macro, etc.
What types of pictures will the second lens allow me to take that the first, basic one won't? I am also considering saving for a good macro lens.Is it more useful to not buy the second lens, buy the $580 camera, and use the saved money for a macro lens?

Thank you.
Added (1). The second lens is $300 dollars by itself.By getting the combined package, I save over $100.Is it useful to therefore buy the package, and perhaps save the lens until I get more experienced? I'm only 18 and don't have thousands of dollars to spend though, and so want to only buy quite useful lenses that can be used often.

Photography advice pretty please?

I was wondering if there's a way I can make the aperture more visible and effective on my camera, because whenever I actually try to get a decent aperture effect it never shows as much as other times. I have a Nikon D3000… Thank you (:
