Watching Haraam

 
As salaam u alaikum Mufti Sahab,
 
I am a 40 year old male . My life history has been up and down as far as deen is concerned. I have been falling prey to sins like watching haram and bad thoughts and chatting etc. I do understand that these are bad but somehow fall prey to them. But i also understand that these are bad, i also pray atleast 3  - 5 times a day. 
 
I also have a problem that when i go to bathroom, after instinja , i feel few drops come out after some time. I try to sit in the bathroom for as long as possible but i have developed a work around but covering the private part with tissue and coming out. Later before wudu i wash the private part. Is this an acceptable work around or should i sit and try to take out the last drop?
 
My major problem is that when i am in salat i do not have khushu and khuzu. Moreover i notice that the persons standing next to me are disturbed due to me in their namaz. I notice clearly that they are feeling uncomfortable and i get this feeling that i am not serious about my namaz. I get this feeling that i do it to show off or to gain worldly benefits. 
 
Please help with these matters asap. Please do not post my name on website
 
Jazakh Allah khair
