Indeed I'm more than willing to help just ping me. Triaging in general shouldn't be frustrating. If directions aren't clear on the bug then mark it as NEEDINFO and ask the user for explicit steps. I've found triaging to have benefits and drawbacks, can be quite tiresome but you learn a ton about the product and see all the interesting and unique things that people use LibreOffice for. Furthermore, it's really the first (and critical) step in getting bugs identified and into developers hands to get fixed.
That being said, I applaud your being proactive - we truly do need more users to take a step from being a user to being a contributor as the workload is just to much for our small team. There are a ton of other non tech ways to get involved - for instance marketing (they always need help) and localization stuff (again, always need help). I can point you in the direction if you're interesting in helping out in some other area.
Best,
Joel
