Designing a Large Poster (Photoshop or Illustrator)

Hello everyone,
I was using quite a lot photoschop cs 2 few years ago. I have not used it too much but still I think I would be able to do some work on it.

These days I wanted to make a really large poster (rougly 0.8 * 1 meter) with some pictures I have captured from a photo camera. I think the pictures are 5 Megapixels and as I want to put small areas of each photo (so I think their resolution should be quite fine).

My major concern is as the image should be large enough, it might be better to try some other program that is known to be able to create scalable images (like illustrator).

1.-Which is the right of program for such a banner/poster?
2.-How can I find what is the required resolution for not having a pixelized print?
3.-How can I find what is the captured quality of the captures photo images? How 3.- relates to 2.-?

I would like to thank you in advance for your help

If you plan to draw scalable graphics, then use Illustrator. If you're only scaling text, then use Photoshop or Illustrator.
2.-How can I find what is the required resolution for not having a pixelized print?

Contact the printing company and ask them what dpi they use for printing this poster, and create your image with the same number of pixels.
3.-How can I find what is the captured quality of the captures photo images? How 3.- relates to 2.-?

Download a photo from your camera, and see how many pixels it has. Let's say it is 2400x1800 pixels. If your printer says the banner will be 300dpi, then your photo can (without scaling up) cover an 8in x 6in area of the banner. It's just math on the number of pixels you have in your image versus the number you need for the banner.

I think Photoshop is good enough for that size. You can increase the pixel when edit the images. Also, you can customize in your actual size. For example 0.8 M X 1 M.

You should find what size units and resolutions your printer prints in, does he use inches, centimeters or what? And make your image accordingly.
