Formulating what kind of users the wall is targeted at might be a good start to get some useful answers.
From your post I speculate you are a total beginner at climbing and you want your 5 and 6 year old kids to use the wall also?
My advice would be:
A ninety degree wall will get boring very quickly but is good for the young ones. Adjustable angle would be the best solution.
Get a good mat or crashpad of some sorts. Especially for the kids.
Invest in quality holds rather than the cheapest deal you can find online. If you really start to use the wall more intensively you'll quickly realise that the quality of the wall is mainly dictated by the holds on it.
Don't bother with bolt on holds, screw on is fine. Unless it's no big deal for you to make your wall suitable to bolt on.
