will this work on super slim versions?

Does not work on Super Slims. PS3 Fats and Slims Cech 250 and below. Ps3 slims Cech 300+ is not downgrade able

i am running 4.75 will the downgrade my software to 3.55 also do i need anything els or does this have the update data on it

Make sure it's downgrade compatible first and foremost, then you download 3.55, you can just google: ps3 3.55 ofw and you'll be gold. Honestly, go through youtube tutorials. when doing the downgrade MAKE SURE YOU CHECK YOUR DUMPS. If you backup your ps3 with bad dumps, say hello to your new paper weight. so yeah

will this work for ps3 slim 4.70?

Here is there main website, http://www.e3-tech.net/e3%20flasher.html I can't promis you that your Ps3 slim 4.70 will support it. Sorry for late response.

Could you remove it after you downgrade and is it suppose to be on cfw or ofw after downgrade

You can remove it afterwards if you want, but it would be a pain. You can use it to flash CFW or OFW. Whichever you want. I'm not sure why you would want to go through all the trouble just to install OFW though.
