I fundamentally disagree with you on your understanding. The above ayat cannot be taken as a general rule. Yes they are applicable in many times but there is not cause and effect relationship.
Many pious people live their whole lives in discomfort and pain. Many a times believers in spite of their taqwa and overpowered by their enemies. So having taqwa does not necessarily mean a believer's problem will definitely be solved in this life. Nor does it mean his life will have no troubles and he will not experience pain and inconvenience.
If you are saying the opposite then please explain why Imam Bukhari died while being disgraced by the people of his city, many prophets were killed by their enemies, and the books of history and hadith are full of it. So many pious lived in inconvenience, and their own children were disbelievers and did not accept their message.
The only understanding of these verses which can be applied as an absolute general rule is that whoever has taqwa Allah will solve his problems and give him peace in the akhirah if not in this world also. In this world it could or could not happen according to the will of Allah - but it cannot be applied generally. If you believe it can be applied generally then it would give me much solace and peace - but I still do not find proof from practical experience of the people of the past.
