I'm planning the same route and my current plan of attack is:
Get the Pak one in the UK, along with the NOC for Balochistan
Get the Iran one in Turkey, where apparently the embassy staff are a bit nicer to 'nutjobs'/less suspicious
From there on the visas get a lot more straightforward.
I'll get the ones I need to get from Aus to Europe via the stans arranged in Aus - might pick them up elsewhere though - such as Ulan Ude for Mongolia.
I've 'lost' visas before by getting them too far in advance and then running into mechanical issues/russian women/vodka along the way that have meant my dates had gone - good money down the drain! (no regrets though  )
Make sure you get a multiple-entry business visa for Russia, they hand them out pretty easy and are well worth it for flexibility.
