I agree with all that John Elison has said.
I'll just add:
1. When using a digital pressure gauge ensure that is is calibrated. Hopefully the gauge came with a test weight. If not the OP will need to get hold of a 5g laboratory weight. To use it with most of these gauges you switch the gauge on, press a button marked "tare" and when the figures start to flash place the weight on the pressure pad and leave it until the flashing ceases. If the gauge has no facility for calibration then it is unreliable.
2. The OP has asked how to set VTA and azimuth. Actually it is Stylus Rake Angle (SRA) which is the important thing but VTA acts as a reasonable metaphor for it in many cases.
So, start by getting the pickup arm as close as possible to being parallel to the platter. Then, using a well recorded disc, listen. Raise the arm height by a small amount. listen again. Is the sound becoming too bright or harsh? Or is it a bit thick and dull? Do you hear a 3D image between the speakers ( this depends upon your whole system set up and particularly speaker positioning as well as the recording). If the arm is too high it will sound harsh and bright, if too low, thick and dull. So adjust up or down in small increments. If you have not done this before it may take a few tries before you will understand exactly what you are listening for.
3. Azimuth. To do this properly you need a test disc and an oscilloscope or a test disc and Fozgometer. On the assumption that you have neither the rough way of doing it is to place a handbag mirror ( I am not necessarily suggesting that you already have either a handbag or the related mirror :-)) on the platter and lower the cartridge on to it. The reflection serves to emphasise any angle of misalignment comparing right with left side. NB: the reason for the more complex method is that with the mirror you are only looking at the cartridge body. You cannot tell by this if the cartridge motor is misaligned within the body.
4. Cleaning the stylus. Always remove the arm from its rest when doing this. By doing this if you apply too much upward pressure the arm will simply float upwards. If you don't then you risk damaging the cantilever.
5. Stylus wear. It is not possible to judge this without a suitable microscope, lighting and experience ( the latter is something that few home hobbyists have in this respect). If you suspect undue wear or damage and unless obvious e.g. a snapped cantilever, send it to the distributor or other stylus expert for assessment. As another inmate has pointed out, the cartridge you have is not he original supplied so any settings as received may be questionable. However it seems to have been OK until a few days ago which indicates either something has gone out of alignment or damage.
