Be careful about "don't bother", it can be interpreted as actively hostile.
It's about like when you say to your other half, "I'm going to spend the rent for the next 3 months on a new motorbike", and she (sorry, it's usually "she" in this context) says "Fine!" when she really does not mean "fine", what she means is "I'm obviously not going to be able to stop you doing whatever immature selfish thing you like, but if you do, then our relationship is over."
In this case, "Don't bother" means "It's obviously far too much trouble for you to just perform this minor courtesy for me, and I clearly cannot rely on you to pull your weight in this relationship, so please be aware that our relationship is on shaky ground as of now."
So if someone offers to wait for you, and you say "Don't bother", it can be interpreted as a rude rejection of a courtesy offered, and the person asking would spend considerable emotional energy wondering what it is that he or she has done to upset you.
Better would be:
"Thanks, but you go on ahead, I'll catch you up later."
Then there is nothing in what you said that indicates that there is any sort of obligation that you need to be waited for.
Even saying "thanks, but you don't have to" is using the language of obligation and duty ("Have to") and can cause awkwardness.
To use X - X here has to be a tool, and to use X will mean do an activity where X will help or is needed to accomplish that activity. E.g.: Use the pen to write down what I say. A pen is a tool that is needed to accomplish writing.
To make use of X - This is like to use X except that X is not necessarily needed to complete the activity in question, but it will help. E.g.: Feel free to make use of anything in my spice rack when you start cooking. The spices might help, but aren't strictly required.
To tap into X - A physical tap is something that allows one to draw out or extract water, liquid, or other similar resource from a stream, network, or container. Following this logic, tapping into something can mean attempting to draw out or extract something needed (from someone) that can help you complete an activity, and this something will not be a physical object but a mental resource such as knowledge, skill, social connections, etc. Tap into your customer service skills when dealing with difficult requests.
So ...
A market in my opinion at least, that can be tapped into. Graduates would more likely be something made use of unless your location is starved for the skills of this specific group of graduates. Tap into X somewhat carries the subtext of X is needed by us but not vice versa.
And,
Can you make use of these papers?
Can you use these papers?
The difference in meaning depends on what the papers contain and how useful they are to the person you are offering to them. If you think they will help, but aren't required, make use of is appropriate. If you think they are needed by him to accomplish his task, use is appropriate.

The phrase "with regard to" indicates that the manager wants to meet you and discuss directly the issue of the theft that occurred in the office.
The phrase "With reference to" indicates that the manager wants to meet you and discussing the issue of the theft that occurred in the office.
They both give out the same meaning, but "with regard to" sets off a more urgent tone than "with reference to".
The phrase "In connection with" may or may not indicate that the topic the manager wants to talk to you about is directly about to the theft that occurred in the office.
