Would I need to be able to develop my own film for pictures using this camera?
You could send the film or paper to a lab capable of processing it, or take it there if you live in a larger city. However, it's actually much cheaper to process B&W film yourself. You already need a totally dark place to load the film holders, and you can use the same place to load a 4x5 daylight tank. Once it's loaded and the cover is on, you can take it out into the light and process it. Look on Ilford and Kodak websites for instructions on the processing part. Other than the tank and chemicals, all you need is a timer and the ability to follow instructions. You can probably find the tank used quite cheap.
The positive paper is done then. If you want positives from the negative you can contact print it on 4x5 photo paper. This you'd have to do in a room that is only lit by a safelight. You can buy bulbs, you don't want red, that is for lith film, you want yellow for photo paper. Sandwich the negative and paper between 2 pieces of clean glass and expose to light. You'll have to experiment with exposure length, that's how it works even if you have an enlarger. You need 3 trays big enough to put the paper in with the chemicals, which are the same chemicals except for the type of developer.
Another option would be to get a good scanner and scan the negatives. Most designed for photo use come with a basic copy of photo shop. Then you just send it to your printer. The big advantage of going to all the trouble is the virtually unlimited depth of field from a pinhole camera.
