Issues With My 2001 Tacoma Prerunner v6

Hello all, first off happy holidays to everyone!

So my tacoma has definitely got a few things going on. For one, the transmission jerks hard until the truck warms up, which isnt to big of an issue for me atm. I plan on doing a transmission fluid flush in the near future. My main thing is that i noticed today when i am accelerating it seems like the truck is struggling and is on the verge of tapping out. It seems like it has no power at all. I am concerned when accelerating that the truck might die (it has twice in the past months but it was because the truck wasnt fully warmed up) Any ideas? I tried the cheap seafoam treatment, but im thinking it could be fuel pump.

Also, my truck is at pretty high mileage about 185000 miles. I have the carfax so I plan on checking what has been done but I want to start going through the truck and replacing plugs, filters, belts etc. Does anyone know what is recommended? I did check the thread that was stickied but it doesnt go past about 120,000 i believe.

Finally i have notice the trick squeaking when I am going below 10mph thought it was my pads but checked and they seem like they have plenty left plus it happens no matter whether im breaking or not. Any suggestions?

Jeez sorry for the amount of questions. Thank you to all who read or respond and have a great Christmas
