In a team, you need to always have the equivalent of RuneScape gold a tool kit (whether bought or bound) as well as laws/cosmics or astrals if you have some extra ess. CRUSH skeletons. Attack fashions are a big thing in dugneoneering. BIND a 2h sword (the best you can get), if you do not have the smithing level to create it, go to'Dung Smith' FC. When You get a Shadow Silk Hood from a nighttime spider, then bind that too - until then, use the highest tier platebody (again,'Dung Smith' FC)

Also is god team generally the best for now? Are prayer potions value the effort/money nowadays considering the nerf to protect from prayers? To begin with, some more general advice: I have been told Dragonrider buys at half the ge cost... but go for Bandos nonetheless. It's super cheap right now. (~6m for the Chestplate and Tassets)

Work towards a Slayer helm, and try to update this to the t70 model together with your slayer points. Now, to answer your query about stab/crush/slash weapons, let me explain how monster flaws work with an illustration. Steel dragons are weak to Water charms. What this means is you'll have the maximum accuracy with Magic (Water charms particularly.)

Likewise if a creature is weak to Crush, such as Jadinkos, this implies melee is the most accurate attack style against them, and Crush is the best style. Comparatively, Range or Mage will have reduced accuracy. (Even though at high levels, your gear is usually good enough that there's no huge difference.) In conclusion, keep your Dragon scimitars, also do not purchase other melee weapons. They'll suffice for everything that is weak to melee.

Likewise, stick to double wielding range and magic. I'm guessing you do not have anti fire potions, so steer clear of dual wielding. Also, dual wielding enables the usage of a shield and the Rejuvination/Resonance skills. Likewise with elemental charms. Personally, I've a great deal of elemental runes stashed up buy RS gold, so that I always just use the creature's specific weakness. It's up to you though, you are going to hit well enough with atmosphere spells.
