Realistically, that few minutes to remove "all that stuff" will save you a LOT of grief in the long run. The things I suggest take what, all of 10 extra minutes to remove?
You dont need to remove the fan shroud if you have electric fan.
Exhaust is a maybe, but most of the time it will give you another inch or so.
Am I saying you cant do it without removing all that stuff?? No, but I probably would question the completeness of the job.
For starters, the extra room will allow you to work so much faster it will often more than make up for the time lost dorking around to get the gasket around the pickup. Unless you get super lucky on cleaning the old gasket material, you need the room to clean the pan and the mating surface of the engine block properly. You also need the room in order to clean and inspect the inside of the pan to make sure you didnt drop any pieces of gasket or dirt into the pan. (I clean inside the pan no matter what.)
While I am in there, I also like to check things out - make sure nothing is excessively worn, remove any build up/other trash, look for any broken or visibly damaged parts, etc. (I once found a chunk of piston skirt in the bottom of the pan on a motor that seemed to run perfect other than the pan leaking!) And if its a high mileage motor, I might as well toss a new oil pump into it since I am right there and its so cheap and easy (just 4 little bolts - 5 if we toss in a new oil pickup while at it.)
Does one have to do that? No, I suppose not. But those are things you probably should do, and which you are never going to pull off unless you drop the pan enough.
Personally, Im not risking a motor, damage to components, nor the need to do the job again (think: leaking pan because you couldnt see a piece of leftover gasket) just because of a few extra bolts - almost all of which are very easy to get to and remove.
Of course, I do recognize that not everyone desires to do as complete of a job...
