Great suggestions given above.
As for range finder....why do you think your Vortex LRF is inaccurate? I have a Vortex Viper LRF and it works well but I also have a Sig 2000 that I use most often (yeah, older model now its Sig 3k or up I believe) and if you get around to wanting to upgrade, I would personally suggest looking at Sig (keeping in mind that there are many, many others on this board with far more experience than me).
The suggestion to use 4DOF app is a good one. Its free and works well.
If you ever plan to reload (or just want accurate speed for your BC), you may want to add a chronograph and I would only suggest the Garmin Xero.
Now, you can shoot known distance targets at range (like 600 yds) and can back into the speed by adjusting MV until elevation matches what you see on the target (e.g. if you are high, increase MV until the BC matches what you see on the target)
Bipods....everybody has a favorite and there are lots of good ones to choose from. Personally, I like my Atlas CAL for a decent price for a good bipod.
Tripod...I have a Two Vets with an RRS Anvil-30 ball head. I'm 72 and do not compete. Perhaps if I did I would go for the more expensive RRS tripod which is kind of the gold standard.
As for evaluating performance...consider software that let's you evaluate/measure groups. I don't personally view my phone as a substitute for a computer and monitor so I don't use Ballistic X app. I personally prefer On Target for $12 for the download.
Other folks (ones that compete) will have better recommendations for bags but a good rear bag is essential (and I like
@Enough Said "The Answer" for a rear bag and you can find his thread selling them on this site).
For front bag I have a Armageddon Gear Shmedium. I use it on top of a tripod, flopping over the sill of a box blind, etc. But as said, the competitors will have better insight as to what would be best for you.
Def go for the Yo Dave trigger spring. I got my cousin into a T3X TACT 1A and putting the Yo Dave spring in his rifle was a game changer for very little money ($10, I think).
Hope this is mildly helpful.
Cheers and healthy and happy new year to you.
