Hello
That looks like a pretty fine selection to me. If anything I would ditch the large diamond and half ball and make sure you get the plain laminated handles and a couple more wrenches if they have some different sizes/thicknesses. You can probably make your own wrenches although I've found them difficult without the right materials.
The half ball
may come in useful if you find a wafer lock and theses can also be tackled with a half diamond or hook but if you want one and need a bit of extra money to spend on handles or wrenches, lose the big diamond, I've never used either of mine.
