Loose Nipples, Bent Spokes, Wonky Rim

Had intended to post a video but something went wrong with the recording will upload if i get the chance. I basically followed this tutorial and the other tutorials by the same guy. I didn't have all the tools so i just flipped the bike upside down on the kitchen table, took of the tire and inner tube(and rim tape) and used a flat headed screwdriver to first undo all the spokes and then re tension them so they would all be the same. However after going all the way round once i realized some of the spokes were warped around the elbow and just seemed longer. I also realized that the rim was badly worn (had been ground at some point but that was worn off). Also the hubs showed signs of wear.

All of this meant that i just wound in all of the nipples until i 'felt' the were tight enough and then went on to true the rim as best i could using the brake pads as a guide. i managed to get it within .5mm of wobble vertically and laterally. After 2 HOURS i felt this was true enough for me, so i took her out for a spin: much better!
