Simple answer is no you dont.
To be honest look on Ebay for jewelers files they can be a lot less, I didn't spend a lot as you wont be using them much.
If you want pliers again look for smooth jawed ones under jewelers tools
For bending I have the BUG from The Small Shop, its big enough for pretty much all you will need.
I also use XURON 440 High Precision Photo Etch Scissor
I hope that list helps and saves you some money
