(1) Definitely your wudhu shall break if urine drops come. When it stops and you are fully satisfied that now no drop shall come then make wudhu and offer salah. If you miss jamah then don’t worry, due to this problem and having the intention of offering salah with jamah you shall get the reward of jamah though you will have to offer it alone.
(2) After using tissue paper you will have to use water too, as it is the best method.
(3) Though no sound comes but if you are sure that wind has passed then wudhu shall break and you will have to make fresh wudhu.
Note: For both these problems you should undergo Unani treatment.
Allah knows Best!
