الحمد لله وحده  ====== 1- yes you can, you don't need to go to iny place, you can make niyat hajj at your place in makkah.  2- yes it's and soap also.  3- I don't understand!  If you mean before ehram of haj, and after performing umrah, my answer is: no problem at all.  But i am not sure what's your question in this point.
