Yes, you should use Upload Request.
For name, you can just use any name describing the picture you like. A lot of requests are titled stuff just like Korra x Asami, EliXUmi, etc. But any name will do, like "Valentine" or similar. They won't be seen in the upload itself so it's just for the sake of giving it a name. And don't worry about tags, I can sort them out myself when I see it.
For link, you'll need to post a link to your translated version. Upload it to Imgur or some other image hosting site if you need somewhere to put it. A link to the source would be helpful too so I can credit the picture, but put that link in the Info box.
And yes, use your name unless you want to reman anonymous (which you probably don't considering this thread).
Info is just for things like describing the picture, links to the original picture, describing why you like it/think it should be added etc. Not essential, but helpful usually.
