Begginings are always the hardest part. You start with only a few books in the middle of uncharted wilderness. If you don't know how this pack works, it will be much harder for you to progress.
Before you waste any resources, know that vanilla tools are useless. So the only 2 way to gain cobblestone without them are either creepers or ex nihilo hammers.
Next thing you want to craft that differs from vanilla gameplay are 4 tables on which you can create and assemble tool parts (stencil table, part builder, tool station and crafting station/table).
Another thing you need to know is that parts can't be created from any material (can be seen while holding SHIFT). First tools are best made of flint (also craftable; use NEI for recipes).
About weapons, there are many for you to craft even from the beggining. Before you gain access to more extended mods, you can use arms from "Mine&Blade Battlegear 2".
You can have up to three combinations for both hands. Use "R" for draw/shealth your weapons and "X" for special attacks (for example shield bash). Many controls have been rebinded due conflicts, so if your "TC wand" or "Traveller's gear" isn't working, check controls in menu first.
There are obviously other rules and mechanics I haven't mentioned but if you are stuck with something and mod wiki isn't helpful then feel free to contact me on discord (Daemon The Hunter#7444). Good luck with your journey...
