Greatly depends on your definition of "lategame", which kind of capabilities do you want to unlock quickly? Because producing 20k iron/second won't help you beat the Gaia Guardian 2.0, nor will a T6 Blood Altar produce RF unless there's an addon for that.
You don't have TiCo, so you probably want a fast XP farm and/or an early tool set. My main suggestion if you're familiar with the mods would be to progress several in parallel: Start Botania as soon as you can or if passive decay is on as soon as you have a treefarm, it has great tools and baubles. Start Blood Magic as soon as you can automate slates and feed the altar whenever you run by, you basically want to reach T4 asap. Get RF going with a mix of TE and EnderIO, their machines upgrade quite well. Do Thaumcraft whenever you have some time to spare and aren't fed up with scanning/researching.
Meanwhile beeline for specific items and mechanics you're interested in, for example with ExtraUtil's Cursed Earth you can farm tons of mob drops, feed an MFR spawner and use that to synthesise materials from specific mobs (redstone+glowstone from witches, wither skulls, blaze rods, ender pearls, villagers for the blood altar if it isn't T4 yet)
For storage definitely use drawers and AE.
If you don't mind ruining the overworld with a quarry you can easily power it by pumping lava from the nether, or with a tree/biofuel farm.
