wow lots'o questions
Well to be honest it's hard to awnser all the questions without knowing what the specs of the cam you have in there are because probably half the questions are going to be based on the cam.
1. (Will strokeing the engine will bring the band down and boost my hp at the same time? and will i still be able to take it up to 6500 rpm or so? or will i need to?) ..........That one is based directly on the cam, the duration of the cam will decide on where the motor makes power in the RPM band.
2.(It has a hydrolic cam which i dont know the exact specifications of, i've heard of issues with big lift cams in stroked engines. Will the same cam be appropriate?)......again without knowing the spec of the cam I cant really awnser that. One thing though, you said your running up to 6500rpms..thats about the limit IMO for a hydralic cam before you start getting valve float.
3.(The carb is a 750 double pumper which i've been told is a little to big for a 355 would it be much nicer on a 383?).....a 750 should be fine for a healthy 383, even a strong 350 can handle it IMO.
4.(I hear that a 355 would be more reliable than the stroked engine? is this true? if so how much more? i'm assumeing that with the stroked engine i can get away with a lower torqe converter which will be nicer on my tranny if i'm right?)........reliability is not something that is based on the stroke of the motor, until you get up to huge cid's where the rod to stoke ratio comes into play. The reliabilty of your motor will be based mostly on the quality of the lower end, and the specs that it was build to when assembled.
5.(Do stroker engines run hotter? colder? like i said its an engine for the street.) ......nope they dont run any hotter.
6.(The engine used to run nitrious and would like to put nitrous back on it in the future. Which option would be better for this?)......again this is a reliabilty question and that is based on the quality of the short block and the assembler that put it together.
7.(I'm on a decently limited budget so should i drop my money on this? or other goodies such as a 4 speed and new suspension i only consider this because of the oportunity of the engine needing to be rebuilt.).....thats a question only you can awnser, if the motor is going to need a rebuild soon as you said then i'd do the motor. A car with new 4-spd and suspension isnt gonna be very fast if the motor is shot
