When I digibitted my LPs I started out by using Audacity’s Repair function to manually remove clicks (Repair is only available in the 1.3 beta version - now emminently stable for day to day use) - actually I started in 1.2 br locating the clicks and redrwing the waveforms. I eventually gave this up as too much hard work and instead invested in a piece of software called ClickRepair. Costs c. $40, but works like magic. See this thread that I started a while back: Click/pop removal - ClickRepair software
