If by avoiding delay, you mean praying any of the obligatory prayers (in this case Dhuhr) with our Sunni brothers at a time before the prescribed time as understood by Shi'a Imamiyyah fiqh. That will not be counted as fulfilling one's obligation, each prayer has its prescribed beginning and ending time.

The obligatory prayers require the fulfilment of certain demands, as stipulated within the risalah amaliyyah (books of ritual practice) if these demands are not adhered to whilst performing the obligatory prayers then for a follower of Jafari fiqh their prayer  is invalid.

for example the recitation of the basmallah (in the name of Allah the all beneficent the all merciful) before the recitation of a surah (a complete one) during the prayer (except surah tawbah), as an obligation.

Or facing of the qiblah throughout the entirety of the prayer as an obligation (not turning the head from left to right whilst reciting the Salaam) which would invalidate the prayer for a follower of the Jafari school of fiqh.

Or the folding of the arms across the chest instead of holding them by the sides of the body. This would also invalidate the prayer if performed by a follower of Jafari fiqh.

Praying behind and praying with are two different things. There is common a mentioning of joining our Sunni brothers during the prayer, as a sign of unity.

However, one is required to observe the correct time and recite all that which is obligatory oneself, if joining the obligatory prayer led by our Sunni brothers.

Allah (azj)  is not an existence which has a location, as that would imply limitation and dependency. 

limitation in the sense of being confined to a space, and dependency in the sense of needing a place within which to exist.

The presence of Allah (azj) is everywhere in the form of power (which manifests in numerous ways). As if it (the power) was not everywhere, there would be no existence for created beings(animate and inanimate). As everything is dependent on Allah (azj)for existence.
 
And Allah (azj) is free from all dependence!

Salaam
Islam does not support this approach, and what we see in daily practice in Muslim and non-Muslim societies is the total opposite of such an unfounded claim.

Studying the religion of Islam is no doubt meritorious for both men and women. But Islam asks us as humans in general and Muslims in particular to meet the needs of humanity. This meeting of needs if we take the medical field for example requires both males and females to excel in the profession. So that benefit might be had by all those in need, here I am alluding to private examinations, as just one simple example. Entailing preferred examinations of females by females, and that of males by males. This  need of society cannot be accomplished if females are restricted to a field of study which does not provide them with the necessary expertise in medicine.

Salaam 

Being poor is not an excuse not to pray, in fact praying increases wealth, material and spiritual.

First, begin by performing your prayers, once that has been done. Other things, like seeing the ahlulbayt in dreams might be possible.

Salaam. As long as the time for them remains yes,  you should perform them with the intention that they are within the time allocated for them. however, if the time has passed for them, then you will have to perform the prayers with the intention of Qaza.
