Unless you are wrenching on bikes for a living, I'd not buy any special tools until you see that you have a need for them. Then consider how often you might need that tool again. I bought a tool to remove my BB back before I knew better and only used that tool once. The BB I put back in the bike required a different tool.

If you stay on friendly terms with your LBS you might find they'll loosen or tighten things like that for you every great once in a while for just cost of a decent round of conversation.

As for Harbor Freight tools, I don't have any problem with them. Just don't expect them to last a long time. I find that some wrenches and other tools don't seem to be forged or hardened as well as they should. Some just break. But I still will buy them when I only will need something a few times in my lifetime. Or it's something that friends like to "borrow" permanently.

Some will insist you have to buy the best you can, but I can buy a crap load of the same HF tool for the price of a really good quality tool. I buy quality tools when I know I'll use them quite a few times.
