You are probably correct in surmising the demise of the 5 cent coin.
Retailers however still us prices like 99 cents even though they don't have 1 and 2 cent coins. So nothing there will change.
Extremely unlikely that the $100 will be overtaken by a 200 or 500 note as the highest denomination. The government hates the cash economy (and tax avoidance) and prefers everything to be easily tracked (automatic payments, credit cards etc).
Retailers also hate cash as it makes it harder for them to build up data profiles on each customers spending habits (store loyalty cards and fly buy cards are a way they get that information on many customers who use cash).
Even if inflation makes the $100 the new $20 in buying power the government would resist any pressure for higher denominations by claiming that the high value notes aid terrorist funding or drug dealers and we must "think of the children" in supporting a cashless and trackable society.
