Sick rig! The F1 is a capable machine, hope you like it! I'd recommend a couple really-nice-to-uave upgrades, goes for just about any bike - get a set of better grips and pedals. I do this on all bikes that I've owned, stock grips and pedals usually suck, partially because companies expect a lot of riders to switch them out for their own personal favs.
I'm assuming you want to ride on flat/platform pedals - get something like the Race Face Chesters, or just Google "best MTB flat pedals under $50" and such, and get something from a brand you recognize. No need to buy super fancy pedals, even like $25 will get you decent pedals.
For grips - these are contact points (grips, pedals, and saddle) so it's super personal. Definitely get lock-on grips though, and get something name-brand so you know it was at least tested. I personally use the PNW Components Loam grips (bonus - they're founded in my home state!), great stuff. Other than that, air up those tires, set your suspension fork, and go rip!
