It rather depends on the beginner, no one size fits all in this game. On that basis, I'd question the merit of including the first three items on your list.
This will be determined by the type of trading they do and the size of their budget. Much of it is free - especially if they're swing trading using end of day data - I'd recommend that they decide which software is best for them.

The choice of broker will also be determined by the market(s) they trade and their account size. For example, £500 or less - then a spread betting broker is the obvious choice. £5,000 or more - a direct market access futures broker becomes possible. But, if they want to day trade U.S. equities, then they'll need USD $25,000 as a bare minimum.
Chances are that most people will already have a computer that is perfectly acceptable - at least for swing trading. I wouldn't recommend a newbie to buy a bespoke machine to trade with. I'd suggest they use their current machine and if trading works out for them - they can use their profits to upgrade in the future if they want to.
