Excepting the squat rack (from which you can do barbell presses)
the other weight training equipment you mention, in my opinion,
is mostly irrelevant and only adds variety.
You can and will get a very result producing workout with just a standard
Olympic set, a set of dumbbells, flat bench and a way to do weighted dips
and chins.
Some of my best results occurred when I worked out in a garage with
a friend of mine and the equipment above was all we had. We had to
make it work.
Except for a short period of time years ago when I briefly joined a gym
(until my friend, the owner, committed suicide), I never worked out in
a gym and avoided them like the plague.
Like I said earlier, and with few exceptions, most machines offer little
in the way of producing noticeable, meaningful, long term improvements
in your physique and only add variety; a break for your brain, which is the
most anabolic organ in your body.
For very little money (and in the long run you will be money ahead),
you can purchase the small amount of the tools required to take you
about as far as you can go. Heck . . . get some friends to go in with
you ($$) and plant it all in somebody's garage and start working out
when you want and in peace and quiet. You just might be surprised
at the results. And no more broken hearts.
