Faedy,
I'd suggest you might need to budget on upgrading the press in the near future.
I'm sure the Super Simplex isnt able to FL size any of the cartridges you mention (Possibly MIGHT do the .223, but certainly not the others).
They arent an overly strong press.
A basic O-Frame press as made by Hornady, Lee, RCBS etc, would be the go, but then you'll need to change your dies, as the Super Simplex uses its own thread to mount the dies. The Super Simplex uses 5/8" dies, wheras the default industry standard for dies is 7/8"x14(First developed by Lee, I think).
NOTE: There is an adapter that allows you to set up the Super Simplex Dies in the new presses:

Also note that the Super Simplex and the Simplex Master are 2 different designs of press; the Master runs the larger standard dies, and is able to FL size cases, due to it's stronger design.
You'll find you'll still be able to do some of the functions on the Super Simplex, but certainly FL sizing will be a LOT more tedious, if you have to do them all in the Simplex method (vice).
I'd also suggest a good set of calipers (digital if the eyesight isnt as keen as 30 years ago), and the Hornady headspacing gauges, so you can dial in the headspace adjustments for each cartridge you load. (Thats if you dont already have both).
Mechanical powder throwers and mechanical scales are plenty good enough to get you started. You can always upgrade them in the future, if you think the convenience is worth the money. A little set of digital scales arent overly expensive(<$100), and can be pretty handy for checking your work.
Cheers,
Rod.
