I'm playing a bit, one of my characters is in a german guild doing random dungeons and ganking, another character I run solo.
You can totally skip all the gathering if you feel it's boring. There are ways to speed it up (a lot), and it can be quite profitable, but you might just as well kill people and sell their stuff and make tons more money that way. Or run dungeons (NOT the expeditions in the town) and make a ton of fame/money from that. I only gather when I don't have time for anything else.
For solo I usually just run into black zones and kill mobs for fame, or preferably I go into blue zone hellgates (not full loot). This character is a week old but with the right build and T4 gear I actually win most hellgates 1v1 and even 1v2, and you get a nice little chest at the end that even in blue zones can have some good stuff that sells for a lot. Sometimes I go into black zones 2v2 hellgates, but the opponents are tougher. If I had a partner, that would be the best way to make fame/money for me, it's super fun.
I think the nice thing about this game is how many different levels of PvP there are. You have your low end stuff that's already quite fun and then a ton of variations in between depending on different zones, full loot or not, small group or larger, solo ganking, zerging, and then GvG at the top end.
If you're lost, just poke me on discord and we'll do something.
