Ok, so i havent used photoshop in a good 2 years and i have forgotten EVERYTHING

So im trying to make a new sig now and i need help.

so question 1

I have an object in a picture that i want to remove, and put it into another pic with a different background, both the backgrounds are different, so how do i do this?

Question 2:

one of my pictures has an inconsistent background, it goes from light grey - dark grey, theres text on the bottom of the dark grey part, i want to move it up to the light grey part, i tried cropping and moving it, but the background of the text is different, i want it to have the light grey background, not dark grey.

2. Same thing, and then move it up (I'm assuming you don't have the .psd file. If you do, then you just select the text layer and move it up).

ok

another question
When im using the gradient tool, the colors keep coming out as black - white
how do u make it so its different colors?

change the colors?...
