Basically the way I do it is go ahead and grab one lead with needle nose pliers, have the board in the air to where you can access the solder point. Apply the soldering iron onto the area between the point and the flat area on the solder area. you will see the solder start to turn shiny. at this point the part you are pulling on will pop off the board. Installing the new part you want to set the post of the new resistor into the hole of the board. hold the iron on the solder area and the part will start to slide through the board. Do this on both ends, make sure there are no voids in the area where the post of the new resistor and the solder on the board meet or you will have to apply a sittle solder. Once you achieve this, ude some wire cutters and clip the excess from the bottom of the board. Basically look at the other components installed on the board and make this job you just completed look like the solder that was done to those and dont let the excess post hang lower than those. This should help you.. (Note: Do not hold the iron on the board for more than it takes to melt the solder or you will burn through the board!!)
