Salaah

Q: I burst a pimple on my thigh to remove its pus, and just rubbed the pus with my fingers, then I wore my undergarment and pants without cleaning the pus and/or blood that got stuck on my thigh after rubbing the pimple, nor did I clean my hands. Now, some amount of pus will stick to my clothes.

Is it allowed or okay to pray in those clothes and without cleaning it (pus) with water on my thigh and fingers or without taking a shower? I read on some websites that a small amount of pus or blood is okay and it will not break the wudoo, but my question is, will the clothes become najis after such activity or shall I take a shower to make myself clean before I pray, or at-least clean only where pus or blood got stuck? 

Q: If I joined the maghrib salaah in the last rakaat or while the imaam was reciting tashahhud of the second rakaat, then how should I perform the two rakaats that I missed, and when should I recite the thana?

Q:

1. I heard that it is more virtuous for a female to pray at the hotel than praying in the Masjid Nabawi or at the Kabah. Is this true?

2. If so, will she be sinful for praying in these Masjids without need?

3. Also, would it be better for her to stay in the hotel than to perform nafl tawafs?

Q: What is the correct zikr to recite after each salaah

1. 33x SubhanAllah

33x Alhumdulillah

34x Allahu Akbar

Or

33x SubhanAllah

33x Alhumdulillah

33x Allahu Akbar

1x Laailaaha illallahu wahdahu La sharikalahu lahul mulku Walahul humdu wahuwa ala Kulli shayin qadeer.

I am confused as I understand both are mentioned in the hadith. Which is the correct zikr to recite after each salaah.

Q: I was performing the Farz of Zuhr. I kinda forgot about the prayer and my mind was wandering about my result which will come in a few days. So I don't remember if I offered 4 farz or just said the salam after 2. What should I do when I have a doubt ?
