Thats easy - you just fold those weak hands

Playing hands in position is important because you now can see the other players
action before you decide what to do. Are they interested in the pot, do they bet
low or high, you get as much information as possible before you have to decide
if you want to throw money at the pot

At some stages of the tournament you can steal blinds with such a card...

Pocket cards 2-6, 3-7, 2-5 are not game cards. Here it is necessary to fold or maybe try a bluff from a position.

You shouldn't be playing those hands very often. If you believe that the players on SB and BB are weak, you could try to outplay them on the flop with those hands, but you shouldn't do that all the time or even them will eventually catch up to your strategy. If the table is filled with good players, it's better to just fold those hands.

When you are in position you will have the advantage to act last. This way you will have more information on your opponents hands. The more information you have on your opponents hands, you have the ability to make better decisions.

Playing in position does not mean that you should always play weak hands ... however it is so important and advantageous to be in position ... that after having studied your opponents for a while you could do a re-raise with one hand weak that you would end up winning it ..!

It is important because as we know poker is a game of incomplete information,by having position you increase your info from your opponents actions.
You can attack your opponent after his check and generally you can show aggression and make him fold even a better hand.

Another very important factor is that you can keep the pot small instead of pump it and go to a cheap show down with a marginal hand of yours. Let's say for example you hold:

and the flop board goes check check all the way down and it is something like that
and your opponent checks again on the river then you can safely bet the river for value because you are sure that you hold the winning hand.

As for the combinations you mention it would be preferable not to open raise them, they are the very bottom of our range no matter how deep stacked we are.
