you are welcome...
your marriage procedure is just fine (its a full fledged marriage)... plus dont fret about it being arranged, thats perfectly ok as per our culture, most happen that way, so i hope in your cover letter you explained that just like you did here... what matters is how you commute after the marriage, this is what they want to see (in your case that is, since ur parents arranged it etc)... so prepare lots of skype, phone, chat, email, etc logs... photos, try a visit (best thing to do, and take lots of photos)... all this will help show the visa officer that your case is indeed genuine... dont go throwing money at wall crazy to show proofs, wasting money is not equal to genuineness of relation (for example, if you send her a $10 perfume or a $1000 perfume, the visa officer will see it as a gift)... so again dont worry about not having any proof pre-marriage... get the post marriage proof ready...
they give you a standard 45 days, and its not a be all end all due date (but obv try to get things in sooner than later: in some cases say if you are having a hard time getting a police clearance certificate and think its gona take more than 45 days then fax them stating that as soon as you get it you will send them the package)... the BFD is not of 45 days, its a little more than that in general allowing you time to get it in and then it being placed within your file... and the officer will open your file on the BFD or in the immediate following 2-3 days... for sure not earlier (you will be lucky if they do, but dont count on it)...
another hint, keep a copy of everything, so basically whatever you send in keep a ditto copy if you can, they can lose your stuff and request again, so have it just in case...
again dont dwell on the waiting, it is a long process, and will take on avg 14-16 months, so instead of becoming devdas, try to keep the wife happy, and communicate more with her gathering evidence for your case
best of luck...
