I do not have either cold or hot water from my tap in the kitchen and the one in the bathroom. The shower and the tub both have water but these two have nothing …. possibly an airlock? tried my thumb over it but heard that if your tank has a check valve or something like that that this method will not work? Also don't think I can get a good seal from my thumb over the nozzle? Tried blocking in the water underneath sink and opening it again with no luck. I had just finished draining my hot water tank and flushing the sludge out of it and don't think we purged the air correctly? Now no hot or cold from only those locations ….

Delta makes a line of shower valves (Monitor 17 series) that has separate Temperature and Volume controls in a single hole package. It approximates a thermostatic valve, which is a much more expensive valve.
The little arm at 2 o'clock is the temperature setting, and the larger one at 4 o'clock is the volume.
It would be necessary to replace both the valve body and the valve trim to use this solution.
I believe you are over estimating how much hot water is needed to fill the tub. It will be filled below the overflow drain that should be built into the tub. You can reduce the total by the size of the person getting into the tub. And most importantly you can reduce the amount of hot water by any cold water you include to regulate the temperature, perhaps you are only using 2/3 hot water to 1/3 cold water.
The important question you'll want to determine is how quickly the water heater can regenerate a full 50 gallons of hot water because you may want to heat the bath back up after a while, or use hot water for some other purpose after taking a bath. If you find yourself near the threshold of available hot water, you may find it easier and cheaper to increase the temperature of the hot water in the existing tank, rather than adding a tankless water heater.

Without being there to see the problem its hard to give a sure fire "here's the problem answer" but Tubs do not have aerators. I'm assuming your sinks both do.
This coupled with the note that you indicated you just drained sludge from your hot water tank leads me to believe you are on well water or hard water, or at least, potentially untreated water.
I would suggest removing the aerator on whichever sink is easy to remove on and then try it. I have seen in my mother in laws house an aerator so plugged that it didn't even allow a drop of water out. Since you disturbed sediment in the tank, it likely set larger pieces free and thus clogged the aerator.
You can usually separate the screens in an aerator and clean them and the plastic diverter/distributor parts and reuse them. Eventually its easier to just replace them, they can be had at any local hardware store for a nominal price. Bring yours with you if this is the case because they have different thread types and sizes and depth.
In the future, when you clear sludge from the tank, run the tub for a good while before trying the sinks. Also, it is possible to plug toilet lines with sludge as well.
