I can give some advice on money making for how I do it, for what it's worth I've been through about 10 ex so far this league but now my build is finished other than incremental upgrades I just have everything in chaos for map rolling.
Commit 5 tabs to trading, 10 alts (drop it to 8 or 1 alch as league gets to that point), 1 chaos, 3 chaos, 5 chaos, individually priced. Commit 1 tab to unid-rare recipe, collect one set at a time id everything else. The vast majority of stuff you drop is going to be terrible but it ends up as alts which build up very quickly. If an item has +life and > 60 res put it in the 1 chaos tab, if it's better put it in the 3/5 tab, if it's amazing price it individually. Anything that has >100% es and flat es and resists will sell especially in this league. Essences of woe are crazy good for making high ES gear for almost no investment, vaal regalia and titanium spirit shields have very few prefixes to choose from so a screaming essence of woe gives you flat es guaranteed then you just need a high % roll and it's easy money. Unique drops are just pot luck if someones made a meta build out of it or not, for example I sold a great old ones ward for 30c just because it's in some meta build and is in high demand, don't rely or expect any return from unique drops. At the end of a mapping session convert your alts using the masters if they are level 6 for the discount then use the vendor to go alt > jew > fusing. Then you can either try and manually link your chest when you get to 200/300 fusing or so, or sell them for ex.
Make an uber runner. Uber Izaro is easy, easy cash. If you can do a 4 key run in 10 minutes or less you can rake it in, this can be especially profitable if you fluke a decent head enchant on something desirable like a rats nest or a high es helm. You can also get a headstart on maps doing this and 60 kills is part of the endgame grind challenge if you're going for 40/40. Not possible to run him every day if you have something like charges & conduits he can one shot even the best geared character, but if you have portals & lieutenants you can laugh all the way to the bank.

Pick a cheap build unless you know you can make a tonne of currency or fluke a skyforths or something. I see people complaining all the time that they don't have any money and they die all the time etc, when the build they're playing isn't even safe for a yellow map before 10ex investment but totally destroys everything once you reach that point, and that investment doesn't even include the cost of your 6 link. The only expense I have had this league was for my 6link because I threw 500-600 fusings at it and gave up and bought one pre-6L for 5ex. Everything else on my build was 20c or less and it can do everything in the game except ele reflect.
For maps it's just gritting your teeth and getting through it, eventually the +1 map will drop. Alch yellows and go, I've been doing Perandus mod recently to try it out but that's no good for map drops, if you really want to push it and have the chaos you can use Invasion but in my opinion you get better results from just blasting through as many as possible. Chisel red maps before you alch them, then vaal T13+. The biggest change I had in playing PoE was when I stopped getting annoyed that the next tier wasn't dropping and just started chaining them as quick as I could and just enjoying the grind. If you completely run out of whatever tier it is you feel you need to run buy a map off a stranger, there's no shame in it people seem to have this thing where they have to do their map progression solo but it's a lot easier just buying a map off someone else when you get stuck. Oh and with atlas it's definitely better buying the maps that you've missed unlocking as it's pointless running a Tier 4 Graveyard trying to get a Tower to drop when you're level 90.
