I just dont want to upgrade my hearts too much and then I cant pick them up from the bosses.
In Hateno village, there's a statue that converts hearts to stamina or stamina to hearts. A child leads you to it and it's (the statue) a quest.
How many bosses did you guys find (aside from the Divine Beast and the ones inside them)?
There are lots of bosses hidden in random places: multiple elemental Lyn, multiple Hinox, multiple Talus, something in the Gerudo desert on the way to a GFF, and maybe knock-off elemental Shen-ron bros, but I haven't tried to catch their attention.

Good tip for people:
Don't sell your regular items. Great Fairy sisters can upgrade your gear with these items.
Don't sell your monster parts (Kilton will buy these and this will eventually be used to get Dark Link clothing.)
Don't sell gems. In Gerudo, you'll need these to for jewelry. You'll also need them to upgrade items.
Don't sell ancient parts. You need these to upgrade you scanner and get other ancient items.
You can sell food/potions from items you have in abundance, extra/unwanted clothing, or bummy equine rejects to someone (might be in Gerudo, can't 100% say where; if you know, share.)
------------------
There's a village (Laurelin*?) very far SE that has a chest gambling game; you can abuse this for 300 rupees (100 per play, 200 net profit (until you cash it ousside, howbowdaht)), but it's very much luck based and can add up considering dialogue and multiple failed attempts/loading previous save.
The most concrete way of making money is the Ridgeland Tower Bird-man research study, given by Branli; can be abused for 100 rupees per 600m glide, possibly more by gliding farther.
-------------------
You can buy every arrow, barring Ancient Arrow, from the vendors in Gerudo Town for the Zora. You'll need 600 rupees for the heat-resistant clothing and 280 rupees for 20 arrows.
-----------------
You need 11,600/12,600 rupees for the GFF, possibly including Great Horse Fairy (revives mounts (maybe you can revive a Stahlhorse?).)
3,000 to by a house + 30 bundles of wood. Various upgrades from a door, to a sign (wall mounted weapons are decoration.)
--------------
The fastest horse with the lowest random stats is the royal white horse, but is the most untamed equine (you'll need 3+ stamina recovery elixirs to tame.)

Now the real question: has anyone found the third location for Hestu?
