Definitely replace it. At this stage, with the rubber delaminating from the case, it could come apart at any time. It's dangerous to use. Near the bottom of the picture there are some bare threads. It is at that point the tire should have been replaced and perhaps only used in an emergency. PS I see from the picture that the rim is quite worn. It's not ...
I would generally default to the drive direction indicated on the side wall of the tire. I know folks that run tires opposite of that recommendation for specific reasons (traction gains at the cost of rolling resistance), but generally, the manufacturer knows what they are doing when they put that arrow on the sidewall.
(Presumption the OP is not over about 100kg, even then, I think my answer holds) Don't worry about the bike. It can handle a lot more than you can. For years I rode with no suspension and never broke a bike. I then got, what was then a great fork - 60mm travel, and did not break the bike. I usually pulled out at more than 1 meters air on those bikes.... ...
Unless you are particularly heavy, I would not worry about size - not that much difference in load carrying between a 2.1 and 2.4 that it will cause a blowout. Blowouts are caused by a tire failure of some description (bead failure, not seated on rim properly or cut to tire are the most common causes). You say "old tire and tube" - how old and what ...
What your bike can handle is usually more a matter of your skill level than it is the bike, at least to a certain point. When you watch mountain bike videos, you will see guys on hardtail "XC bikes" take drops much larger than 2 feet. BUT, they have skill, lots of practice, and likely many broken bikes or bones, or both in their past. Don't worry about ...
That does not look like a 28 decimal That is a 28 fraction and that is not a 700 (622) Sheldon Tire Sizing
You must replace it. This tire is shot. I'm curious as to the brand/model of rims as well as the bike itself. Also, what surfaces are you riding on/
I use 23mm and 21mm tyres on my Mavic Reflex rims. It's fine.
