Has anyone used higher rate chargers(say, from a tablet) to speed up charging their iPhone? Will it help/hurt my new phone I haven't even received yet? I plan on using a factory extended cable with the supplied wall charger. New to Apple and just curious.

I often charge my Apple devices, including iPhones using an iPad adapter, and it certainly wont hurt it or damage it, but I think that it depends which iPhone you are using, if you actually get faster charging or not.
iPhone chargers are 5 Watts, and I know of three different iPad chargers (depending on which iPad you buy), I have them all. One is 5 watts (just like the iPhone), one is 10 watts and the other is 12 watts.
The SE is mostly built using a lot of iPhone 5S parts, and from what I understand, the iPhone 5s will charge at 1 amp, regardless of which charger it is plugged in to.
Starting from the iPhone 6 and up, those iPhones allow faster charging if they are plugged into a more powerful charger, like a tablet or iPad adapter.
Apple did give the SE a slightly bigger battery compared to the iPhone 5s, but I do not know if they have allowed it to charge at more than 1 amp. I would probably guess that it remains the same as it was on the iPhone 5s, though I sure wouldn't mind being wrong about that.
The easy way to find out is to just charge the iPhone SE from 0% when you get it using both chargers, and you'll quickly find out if there is any difference.
Along with parts bin components, iPhone SE packs in new hardware including a Skyworks SKY77611 power amplifier module, a Texas Instruments 338S00170 power management IC, Toshiba NAND flash, an EPCOS D5255 antenna switch module and AAC Technologies' 0DALM1 microphone, the report said. A separate as-yet-unidentified chip could be a new power management IC designed by Apple in cooperation with Dialog Semiconductor.
