This isn't going to get it done. We need more information!
What beam; how are you feeding it; what is it's configuration; what is it mounted on???

If by "set the swrs", you mean "adjust the antenna for optimum", it's a process of adjusting
a: The feedpoint
b: The lengths of the elements
c: The spacing of the elements
d: The height above average terrain (HAAT) of the antenna
and maybe a few other items, to simultaneously produce a nearly 50 ohm resistive feedpoint impedance, with acceptable forward gain and front-to-back ratio. As Master Chief said, all of this depends on just what sort of yagi you have. Just saying it's a "3 element" beam doesn't tell us much.
As far as "how to quit pickking up radio stations" -- that's what the antenna's SUPPOSED to do when you're not transmitting. Exactly what do you mean?

Oh, I don't think it's quite the same thing at all. If 'yellowjacket' will give some more information I think he'll get all, or most of his questions answered. Sounds more like an, "Oh S***, what have I gotten into?" than anything else.
And if I'm wrong, it certainly won't take long to find out - lol.

Got a question about picking up radio stations. By this I believe you mean commerical radio stations music and such. So i want to know do you have a preamp and is it much worse with the amp on? Also is this worse above 40 (27.405) as you get into the freeband?

well no use answering this 
theres going to be long posts about it so just pick out what you need to adjust the beam...lol
BTW I don't think anyone in there right mind puts up a beam without measuring it! he said SWRS meaning SWR....
