Repeating salaah if one finds impurity on one's clothing

Q:

1. If one finds any impurity, like a small amount of stool on his clothes, would the clothes be considered napak and would the prayers offered with such clothes need to be repeated?

2. What amount of a najasat renders a cloth napak and impermissible to pray with?

3. If I need to repeat the prayer, would only the Fardh and witr be repeated or also the sunnat and nafl?

Sticky liquid coming out after ghusal

Q: Yesterday I performed ghusal for janabat in the afternoon and urinated two times. One time before ghusal (after discharge) and one time during ghusal and did not see any manni. But after that, the next time I urinated was this morning and some drops of colourless sticky liquid came out after the urine. I also have pain in my kidneys from yesterday. Do I have to perform ghusal again or not? 

Being unable to wash one's feet in a basin for wudhu

Q: From birth I have a congenital hip dislocation problem due which I am not able to lift my leg till the height of the wash basin. In most offices, people wash their feet in the wash basins but I can't do that to wash my feet.

Please advice if I can:

1. Do masah on my feet.

2. Wet the complete foot by rolling a wet hand.

3. Use a commode to wash my feet where a Muslim shower is available.

What is mani and mazi?

Q: I wanted to know what exactly is mani and mazi. I know one is thick and one is thin but what about the excitement thing? Mani means you have to have a ghusal and mazi is just whudhu, but I'm not sure what they actually look like. Is mazi like water (just liquid) or is it a little bit thick and strechy?

Doubts regarding ghusal

Q: What if I do ghusal and then also attend salaah but later I have a doubt whether the ghusal I did was valid or not. The reason being that I think the water didn't wet all the hair on my body. Should I do the ghusal again and repeat the salaah which I attended?
