As for tire size 185/70/14: 185 is the width of the tire in mm; 70 is the height of the sidewall measured in a percentage of the width so 70% of 185; and 14 is the size of the rim in inches.
As for wheels, you will need to make sure about offset as this determines how far in or how far out your wheels will look in reference to your fenders. I believe some people refer to that as either being flush with the fenders or being tucked. From what I understand the Camry normally wears wheels with a positive offset. Offset is actually measured from the center of the rim's width and that's where things get tricky.
Positive offset wheels are any wheel with a mounting surface forward of the centerline.
Negative offset wheels are any wheel with a mounting surface behind the centerline.
The tricky part is if you have a 17x7 wheel with a 45 offset and a 17x8 wheel with a 45 offset. They will not look the same on the car. Oh and to complicate matters more, offset is measured in mm as well even though the wheel is measured in inches. So a 45 offset wheel means the mounting surface is 45 mm forward of the centerline. If you take a 7 inch wheel, divide that in half to get 3.5 inches, convert that to 88.9mm subtract 45mm from 88.9mm to get 43.9mm which represents where the edge of the rim will sit measured from the mounting surface. You can get an idea of where your wheel will sit in relation to your fender.
Oh and don't forget that the more positive you make your wheels, the quicker your car will turn in initially when you corner but then you'll give up some high speed stability. The inverse is true in that if you get less positive wheels you will give up initial turn in when cornering but gain some high speed stability. Not much but perhaps just enough to notice.
Moving on to the diameter of the wheels: I like to use this calculator:

Just plug in your stock wheel size and play around to see how the wheel and tire size effect your speedometer readings in comparison. It's a pretty neat little tool.
