a little help please.

I use photoshop 7.
 
I am having trouble with my layers. For some reason if I wish to move a layer around and position it diffirent I have to hide the layers above it or it clicks to them and move them. I also have to put the layer I want to move on normal or it clicks on the layers below it.

For example if I have a text layer and I want to move the text some where else on the icon I have to blow up the icon to see the text lines better click on the actual text and move it. If I don't it moves the layers below it or above it.

Normally if you select a layer it says on the layer and not move around to others.
how do I stop this?

Also is there an easier way/ perminate way to get ride of the little 01 in the top left corner instead of hitting Ctrl H all the time?

I hope someone can understand this. ^_^;
