Wa `alaykum As-Salamu wa Rahmatullahi wa Barakatuh.

 

Yes a new Muslim can use a book or a brochure to instruct him/her on how to make prayer. During obligatory prayers, he/she should not have excessive movements.

 

As for making prayers for guidance, you do not have to make it at mosque. You can do it at home too. It is necessary to know that you offer two supererogatory rak’ats and after finishing them you recite the following supplication:

 

O Allah, I consult You through Your Knowledge, and I seek strength through Your Power, and ask of Your Great Bounty; for You are Capable whereas I am not and, You know and I do not, and You are the Knower of hidden things. O Allah, if You know that this matter (and you name the thing on which you seek guidance) is good for me in respect of my faith, my livelihood and the consequences of my affairs, the sooner or the later of my affairs then ordain it for me, make it easy for me, and bless it for me. But if You know this matter (and you name the thing on which you seek guidance) to be bad for my faith, my livelihood or the consequences of my affairs, the sooner or the later of my affairs then turn it away from me, and turn me away from it, and grant me power to do good whatever it may be, and cause me to be contented with it.

 

Allah Almighty knows best.
