Need help deciding which adobe product to purchase (Photoshop or Illustrator)

Question

hello,
I am about to be given the task of creating the graphics for my company on a specific task.
We recently got a new printer to create cards with and before now, everyone has been running into trouble getting clean, accurately colored prints for these cards, and I am being given the task of creating them and need to decide what program I will need to achieve this.
What happens, is a company orders a set of cards and sends their graphic, which I will be receiving at a different size than will be needed for printing, so I need to enlarge it, which distorts the colors.
Also, on almost all of the images, I will be needing to add some words to the graphic before printing it, like the company name or address etc. but then occasionally, I am given some general images and generic instructions which I need to follow in order to create the graphic.
So, I was thinking that photoshop would help me to refill the colors after resizing an image, or when I need to create the graphic mostly myself, yet I will be having difficulty creating the words required.
But then illustrator would be giving me excelent fonts and words since its a vector program, yet I believe I will run into problems colorizing my graphics once resized.
So, what does everyone think would be the better option here?
Or what would be a good work around for either photoshop or illustrator that would help me resolve the problems arrising because I do not have the other?
Or what are some other potential problems I might possibly run into?

Well exactally,
Being the economic misfortune that hit the country, my company doesn't have the funds to pay for a professional and they are trying to find a way to keep the project inside the building.
me being 20 years old and wishing to pursue a career in graphic design sees this as a great opportunity to learn alot about printmaking as well as how to use graphic editing programs on a level higher than taught in school.
My boss is wanting me, and going to pay for me, to go under several hours of training to accomplish what needs to be done, but like I said, I am given the task of trying to figure out what kind of software I am going to need for the task, which is why I am here asking about the programs.
Also, it is kind of my first attempt at trying to further understand exactally what each of the programs do, and so far, I have learned quite alot by searching around and asking what other people think.
So, If you don't find it to be too hard to put your opinions or thoughts about how I could best accomplish creating the cleanest cards I would greatly appreciate it.
Sincerely,
BeeHiver
