The short answer is that a 0.35 factor lens is wider than a .45 lens. The factor is used to multiply the normal focal length of your lens, so if you have a 20mm lens, the .45 would convert it into a 9mm lens, while the .35 would make it a 7mm. The difference between 7 and 9 may not seem very large but each mm makes a BIG difference. However, you call it a "macro" lens, but this is the term used for lenses that do almost the opposite of what you want, i.e., they enable you to get a lot closer to the things you photograph, making the objects look larger and actually restricting the field of view. So I don't think you really meant that.
Not sure what you mean about looking like a carnival fun house but you may be referring to the fisheye look, where the field of view is expanded by distorting (bending!) the image to cram more in, especially around the edges. I like and use these lenses, but your mileage may differ.
You might like to note that there's a limit to the angle of view you can show in a photograph: as the angle goes up, the perspective becomes more and more extreme. There's also a physical limit, 180 degrees is the absolute unattainable maximum, and things start looking very odd at about 120 degrees. 100 to 110 is about as far as you can reasonably go.
Don't worry about sounding like a dummy. Real dummies don't ask questions, so they never learn!
Oh yes. The definition you get from such add-on lenses is generally not that great. Before you spend any more money, try one in the shop, take the camera home, enlarge the image on your screen and see if you think the quality is good enough. There is often a "sweet spot" aperture--larger or smaller than that produces more blurring. F5.6 or F8 is a good aperture to try.

Thank you for the reply and the tips. I guess it will take some time for what you said to sink in. I am a hands on learner and so its not sinking in really well. It amazes me how folks like yourself know all these things, I have a long way to go!

Hi, Corrie!
I've been around long enough to pick up some knowledge along the way, and things were less automated when I started out in photography, which meant learning a lot of stuff that isn't needed so much these days. Please feel free to ask about these things, and I'll do my best to reply. The main thing is to ENJOY photography... Have fun!

Just get a Sigma 10-20mm 1:4-5.6 DC EX which is equivalent to a 15mm-30mm on that Sony which you and I both have with a 1.5 Sensor and you get extremely wide images of entire city blocks such as the attached and indoor images that I use for Real Estate Photography also.
