Hi Kpearson;
Dont know if u got required information. For travelling to Pakistan better you get visa from Pakistan Embassy in your country so Pakistan goverment knows before your travel your details etc. and travel dates its good for your own security. For Visa requirements you only need to mention your purpose of travelling and days etc. and if u know already ur address there. Normally you can get visa on arrival but its good to get one in advnace to be on safe side.
Islamabad safe, accomodation etc depends on what is your budget and exactly how many days or months you want to stay, as to find a place for rent and then to furnish etc will take time and logitics efforts, you can find guesthouses also in main sectors.
let me know if you want particular informaiton, I am expact from Pakistan and in Kenya.
rgds,
Hamid
