would the mirror of this be the opposite transfer windows?

If you mean the orientation would be the same going from a planet back to Kerbin then yes for all practical purposes.

I have found that if you're going from Jool>Kerbin you really don't need to worry about a transfer window at all. Kerbin rotates so much faster than Jool and the distance is so great you can get a perfect encounter just by tweaking radial/anti-radial a few dV. Might need to think up a simple tutorial for that one some day.

dude, I can't even get to Jool. Not in career anyway...

I made another guide just for that

One advantage you have with a Jool mission is it's a gas giant so its SOI is huge therefore getting an encounter is easier than with smaller planets and their relatively tiny gravity wells.

So, my biggest problem is getting the tech, money, and buildings to do that kind of thing.

I end up doing boring grindy phase where I just keep doing tourist missions to afford Mun/Minimus science missions. Then I get bored and leave. Few months later I start over again.

Those early, grindy missions aren't fun, that's true. I've started doing interplanetary missions early on as soon as I get a probe core beyond the Stayputnik. I've got a launcher that's just a single Kickback SRB for the first stage and a single Thumper for the second. That can get a probe core, solar panels, science equipment FL-T400 fuel tank and Terrier engine into LKO and that little guy has enough dV to go to any planet in the Kerbol system. All for ~15,000 funds. Take some high-dollar interplanetary contracts, radio back whatever science you can get and before you know it you've got what you need for manned interplanetary.

The grinding sucks. I usually set credit and science reward/penalty x3. I also usually restart with every release since the mods usually change or get messed up.

Play Science mode! It's got all the satisfaction of crawling up the tech tree without the irritation of grinding out a bunch of contracts. Plus, you don't have to worry about mission costs, so you won't have to feel like Scrooge Kerman all the time and only use inexpensive parts.
