Fender Marauder Mod advice?

Hey yall! I've been playing for a few years and I want to get into modding my guitar, it's this discontinued fender marauder from 2013. I was hoping to get some advice/info!

First I wanted to swap out the bridge because I when I bought the guitar it didn't come with a whammy bar and all the bars I've tried don't seem to fit! I've heard that I need to know the screw spacing? But I can't seem to find much info about the stock bridge anywhere, do I just measure the distance between the first and last screws with a ruler?

I also want to swap out both the pickups, while the triple bucker looks AMAZING it produces so much noise that I've decided to just scrap it. As well I've heard that replacing the pots could help improve the sound, however I'm not certain about what to get in that regard, any tips?

Finally I was thinking about tackling this endeavor myself, however I have next to no soldering experience: should I just pay someone else to do it rather than risk damaging the gear?

Any advice/tips/info/resources will be much appreciated!! Thank you!!!
