I'm almost 2 years on this and I still haven't done half achievements.
Machines to use, I recommend the 4% Great Success ones. 8% Reduction time is useless when the bottleneck is material availability in the long run, even if you have access only to the 3 basic crafting lines. Plus the 4% will help gettnig those Great Success achievements too. You cannot have both the Great Success one and Cooldown reduction time for the same type of crafting, but you can have (for example) 4% Great Success for Extending, 4% Great success for PA, 8% CD Reduction for Technique and 4% Great Success for Timed. So go with all 4 of the 4% Great Success ones. You can get them with Excubes and some FUN points I think from the Recycle Shop.
So as to not lose track, start with one category. Most straightforward one is PA crafting. Work on that in a manner so that all PA craft achievements are at an even level. Some of them will progress faster than others because of Daily Requests. Second easiest is Tech Crafting, where you will again work in the same manner.
If you run out of materials for one type of craft, then move to another to save time (and possibly inventory space too)
Do not use Full Charge Lillipariums unless every single of your crafting lines is on cooldown and for longer than 3 hours, and you have materials ready to put again all crafting lines in use. I select 3 hours arbitrarily as it works for me. Try to keep all lines working "in parallel", meaning that they come off cooldown at roughly the same time, so that you don't have to go to your Room every 10 minutes. Use Mini and Small Lilliparia to help with that when you have crafts of different cooldowns. Try to put the longest ones right when you are going offline to again reduce active time needed.
The rest I guess will be covered by @theimporter.
