Thought it must be something like that - forget current measurements at the moment unless you have access to some very expensive equipment that gives you the figures after you plug in track width and thickness. The usual way is to unsolder one end of the component and put the meter between the solder pad and the unsoldered end of the component - not an easy task for the untrained (I some times make a mistake and break a component and I've been doing this type of work for over 30 years). When measuring voltage use the 'gnd' test points for the negative probe of your meter and be careful when applying the positive probe that you don't short anything out - could be very nasty.
For someone with little experience you are doing quite well so far. Just take care and we should get there.
