I have a habit of having too many irons in the fire to keep track of easily (thank God for the BiblioCraft Clipboard). This helps ease any frustration I might encounter by being able to take a break and do something else productive. As stated above, usually the next project or two will either solve my issue or give me time to cool down and insight into how to fix it.
That said, I've been in your place before; balls deep in TC with almost no other mods touched. I have to say, TC has an answer for almost everything, so once you get last the drag of scanning a the things and bottling your first node or two, you don't actually need much outside help. If you're still interested and having fun, that's the goal, so keep up the good work. If you feel like it's becoming a chore, go fiddle with something else for a bit.
If automation is your goal, you can work on some basic tech mods for pipes and the like, or you can use what you have available to automate the world. Golems are a bit deeply, but usually easy enough to use to get by - in fact for some tasks, they are my preferred method of automation (oh, how I love you, Lumberjack Golem). Azanor included many ways to automate the needs of his mod, so if you decide not to hang up the robes, you can still get things going without you touching literally each component every time you need something.
If the tech side feels too far behind at this point to bother with, delve into Botania a bit, as the two mods have a nice compliment to one another. It's definitely different, bit parts of it help your TC, so it's still pushing you forward in your current theme. It also has a flower that acts as a searchable storage management system, although I've never actually set one up, personally. This could stand in for AE2 if all you were using it for was storage.
Blood Magic, too, has integration with TC, and feels completely different from either of those. Automating BM Slate production using Golem minions just feels right somehow.
Options. The blessing that is modded MC. Have fun.
