Sis, the aqeedah issues aren't to do with any madhab or fiqh issue. The aqeedah issues - all of the Muslims have to agree upon them. Since they make up the foundations of our beliefs. So we don't have differences of opinion on them as Muslims, and if people do - this is what causes sects. [most of these sects began from influence from outside religions from other countries which mixed with the new followers of Islam, so their cultural religion was mixed with islam to form the new sects. look at
wahdatul wujud for example - its a hindu concept but certain sufis believe in it which makes them go astray from pure islamic teachings].
I've read his book
Fundamentals on Tawheed, and i believe that if you read that - you would find nothing wrong with it (you'd probably even question what the person meant when they said you shouldn't read it - since its got nothing controversial and its backed with Qur'an and Sunnah for all chapters.) This usually isn't the case with other sects books.
The main issue with people from pakistan and india etc is to do with issues such as waseelah etc. and i'm paki too, with a similar background to what you're going through. By going past that barrier, i've noticed that you don't need to be called 'salafi' to follow the way of the salaf - you just need to practise their way, so long as you keep the principles of islam as your first priority throughout your life.
i.e. its not compulsory to blindly follow anyone except Allah's Messenger. [although you can do taqleed in fiqh on certain issues due to a lack of knowledge of ijtihad etc.]
That you stick to the aqeedah of the salaf, since they followed the way of the sahabah - who followed the way of Allah's Messenger.
Aqeedah is soo important and its the first thing we should learn as Muslims, simply because our Islam stands upon that. For example, if you ask a certain ash'ari
(who is knowledgable on his ash'ari beliefs, remember many who claim to be sufis say they are ash'ari in aqeedah) if Allah speaks - he will say no. He will say that Allah doesn't speak since that is being similar to His creation, rather Allah creates speech - so the Qur'an is not Allah speaking, but something which Allah created of speech and Angel Jibreel spoke to Prophet Muhammad.
You know who Abul-Futuh is? He is the Ash'arite who would leave his mosque, wearing thick armoury, mounting his horse, and then proclaiming in public: "This Quran is not Allah's Speech! This is just paper and ink!" while the Muslim population of Baghdad would stone him and throw filth at him. This was your past, and this still remains your present. But you simply do not have the courage of Abul-Futuh.

Whereas the salaf said that Allah speaks without His speech being similar to the creation. And that Allah really spoke the Qur'an to us.
Now see how these issues are totally crazy and against pure Qur'an and Sunnah? That's why salafis study aqeedah first of all [so they know what they need to know to enter jannah], whereas other sects teach other issues without actually teaching aqeedah properly first. I'm not saying all, but generally.
So what would be more convincing? To study aqeedah with someone who has firm foundations for his faith - backed with Qur'an or Sunnah? Or someone who learns other issues without even knowing what he needs to get to jannah?
I can really tell you through experience that if someone told you to study aqeedah and you asked any good books, they'd simply have books on telling you that Allah exists and that He created everything, and some will inform about Allah's attributes [if the book was for simple people]. If they had to define what 'ibaadah is, they wouldn't. They'd simply say its 'sajdah' and the pillars of islam, and thats it.
Now you might wonder why i'm saying this, but when somethings the truth. It becomes apparent, even if people try to hide it or prevent it from shining forth. The truth seekers, Allah guides them. Ask Allah to guide all of us, ameen.
