SVG Manipulation in Photoshop

Still finding this whole process extremely difficult as I am not an AI user typically.  It seems like there should be a simple solution to allow me to paintbucket in colors into areas of the image with defined borders.  Yes, the file is an SVG, but I don't need paths for cutting, etc, just a copy of the image at face value whereby I can pick a color, drag the paintbucket to the appropriate area, and fill in that area with the selected color, rinse and repeat until the picture is colorized for sublimation printing.  I've tried selecting all and using pathfinder to make an outline which I assume makes said outline an object but I keep getting a duplicate of paths.  I've tried melding/welding all the paths so it is one continous, but no useable results.  Maybe I should simply screentshot the image and use paint for my needs, adjusting the printout until it roughly matches the size I need it to be to sublimate onto the prepared blank shape.  KISS I guess.  🙂

Thanks for the replies.  I do have the Adobe Suite, so I will attempt to import the portion of the SVG I want to colorize into Illustrator as suggested, then figure out how to manipulate the file (maintain outlines and overall proportions while colorzing areas as appropriate).  Hopefully it is as easy as using the paintbucket to fill the areas in (zero experience with Illustrator and some background in Photoshop but that was light years ago, hence my initial inquiry about using PS).  Does AI allow you to import colors, as a lot of the time I will be looking to match sport team colors and found a website that lists the Pantone, Hex, RGB, and CMYK values?

Absolutely agree with the above, but I'd put it even more strongly: don't think of doing this in Photoshop. This is an Illustrator job.

Photoshop will rasterize your vector files. That is probably not what you want. 

For a pixel graphic the relevant unit is the pixel. If you need to convert that into inches (or cm) you need to define a pixel density. So whatever parameter for pixel density your engraver uses, you need to put that in. If your SVG uses the same density, it should be OK to place the SVG in Photosop. 

I agree with @c.pfaffenbichler, you should use a vector program to do whatever you intend to do.
