This will be my second BIAB recipe and wanted to get some critiques on it. Can the BIAB be done like extract where I can make a 3 gallon batch and just add water to get to 5 gallons or is it best to keep it to one size? I was thinking the mash temperature should be around 145-150F @90min but should there be any other rest that it could benefit from?

Yes - you can top off if you want. I would not top off though. The full wort boil helps drive off chlorine, allows complete water treatment, and is more sanitary. The trade off is it takes a larger kettle, and a chiller of some kind. Not sure what the wheat starch is for? I can't tell if this is a 3 gallon or a 5 gallon recipe, need to know that and the efficiency to provide more feedback.
Its a 3 gallon recipe and I want to make at least 5 gallons but I don't have a pot big enough to support 5 gallons. If its better to do a full volume and not top off then I'll just make two batches and have 6 gallons. I'm not sure what the wheat starch is for either. I seen in it a few recipes and trying to research it to find out what it does. So far my efficiency is 68% but I've only done 1 BIAB batch.
68% is fine for BIAB. Two batches, topping off, or jump up to a 15 gallon kettle so you can do 10 gallon batches
Hopefully soon I'll have a 15 gallon kettle but for now I'll work with what I have. As far as the wheat starch goes I can't find much about it. It seems to help with attenuation of the beer and brewhouse efficiency.
if your doing bib in a small pot to add water later your going to need to either brew a thick mash for a long period of time and use a 5 gallon recipe or do 2 batches back to back with 3,otherwise your efficiency will go way down and you'll have watered down beer
