Ninite software. Convenient but has too much access to your pc. Just make sure all the stuff is hooked up correctly, monitor temps at low and full loads (HW monitor), CPU overclock use your bios, GPU overclock use MSI Afterburner. Bunch of benchmark softwares out there, some free; some for a fee- 3DMark, Unigine, etc.

CPU-Z and Openhardwaremonitor for monitoring, MSI Afterburner for GPU monitoring and overclocking, 7-zip, Cinebench if you want to benchmark a lot, Passmark Disk Checkup for monitoring HDD health, Malwarebytes free and maybe check out Rainmeter if you want your desktop to look extra nice. There are probably more I'm not thinking of.

Try Ninite. It is a really easy way to get everything you need.

First thing (after installing drivers), install antivirus (AVG or Avira have good free versions), Malwarebytes, and Chrome adblock.  Do these first to protect your from scammers who try to get you to download malware disguised as free software you are looking for.
