You do not need a screen or a sd card reader, but they are nice to have. To start with you can control everything from a computer.

Electronics is a personal choice..

Will depends on your answers to these questions.

8 bit or 32bit
what firmware do you want to run marlin, smothieware, reprap firmware
On board or replaceable stepper modules
extra features like wifi support or Ethernet, or additional extruder support

Most 8 bit boards are electrically equivalent, same family of processors running at same speeds running the same firmwares. Only minor differences in pin layout and number of mosfet
Some 8 bit boards do have better thermal designs than others.
8 bit is cheaper way cheaper

The 32 bit market is different there are two main competing types those that run smoothie and those that run reprapfirmware.

all boards can be driven by a raspberry pi running octoprint for wifi and Ethernet support, 32 bit board tend to have wifi and Ethernet inbuilt

There are some on here that insist that their 32 bit duet is the only answer, this is not correct.

Thats a standard ramps 1.4 board.

its 8 bit and will work fine

On you second picture you have

1) a tealight candle tongue sticking out smiley
2) ramps stack (pololu drivers on ramps 1.4 board on mega controller)
3) a thermistor (glass bead with two copper legs, NB these are fragile, treat with care)
4) a assortment of cables
5) a sd card module for ramps
6) looks to be heatsinks
7) mechanical endstops
8) a fan

It looks like reprapdiscount gear, which is actually good quality stuff

you need:
stepper motors (x5)
power supply 12v

plastics and rods and nuts etc for a frame
linear rods and bearings for movement

lots of nuts, washers etc to put it all togeater

if your planning on a heated bed, you also need
heated bed
another thermistor (your hotend may already have one in which case the one in the picture is for the heated bed)
