Hi, it is also important to try hard for exams simply for the reason of actually learning the material. Year 1 is really about gaining knowledge and second and third year is about applying this knowledge, in terms of essays turning from descriptive to being about analysis and critical evaluation, and if you go on placements etc the knowledge you have learnt in your first year will serve you well. The reason grades don't count in your 1st year is to allow you to absorb the knowledge without the worry of failing, so that you can take the proper time to learn it. As long as you are putting in the effort to revise and are retaining some of the information then you will be in a good place to go into second year. Some exams are harder than others and you don't always get the mark you thought you would have, but that's okay. It then gives you the opportunity to see where you can improve.
Often second year counts as 25% of your final grade and third year counts as 75% of your final grade. Doing well in first year will help you do better in second year, which is the hardest academic leap, more so than even second to third year. Unlike at school, at university you don't get predications, and first year does not factor into this at all. I have never been asked for my university transcript from an employer, they will just look at your final grade. If you come out with a 2:2 or higher then you will be in good standing for getting a job.
In terms of them writing you a reference, they will also write about things other than just the marks you receive on exams and assignments, for example, if you use their feedback to improve, they will write about your character (it's usually your personal tutor or course lead who would write a reference so over three years they should know you quite well) and if you are a course or department rep they can write about that. I wouldn't worry so much, as long as you try to the best of your ability, as people will see your effort and recognise you for it.
