any and all tips please?

hi everyone! i’m a ftm with a two week old and i think things have been going okay. i currently feed baby on demand and breast only but i’m hoping to build up a stash and eventually have it so my partner can give baby a bottle so i can rest a little more. any tips for how to pump? i’m not sure when i’m supposed to do that, i’ve tried but i feel like baby nurses too frequently and they want to nurse so soon after pumping idk that they’d get enough. also any tips for bottles and pacifiers for breastfed babies? we have a bottle we tried once and the latch immediately had issues at the next feed. any other tips/tricks are more than welcome because i have zero idea what i’m doing and i don’t know what i don’t know. thanks in advance!!
