Got a Flashforge Creator. Where to start?

I was lucky enough to get a Flashforge Creator from a friend and am having a tough time getting started. I've tried to level the bed the best I can. With some hairspray I was finally able to get the first layer to stick and my first print is in work.

1. The software in the manual hasn't been updated in years (ReplicatorG) and I can't get it to install on my PC. I've found some STLs on Thingiverse and downloaded Cura. Unfortunately the Creator doesn't show up in the dropdown. Is there a place that I get the specs for adding the printer manually? Or is there a better slicer solution for such a noob to make slices?
2. Since this printer is really old, is there any firmware I need to upgrade?
3. Any general tips for getting the most out of this printer?

Sorry for such basic questions. I'm so new, I don't even know what to search for in Google.

Cura Profile for FlashForge Creator Pro

Thanks. It seems like there is a bit of confusion if that G-code will actually work. Is there danger of just trying it out or am I at risk for crashing something?

Oh hell no - NOT cura !
1) it's crap
2) it won't work :-)
Your machine uses x3g files NOT raw g-code.
You want Flashprint
During install, tell it you have a creator pro.
It's a great slicer, really easy to use and the only slicer I've ever had any luck doing dual extrusion prints with.

And it knows you need x3g files :-)

the next thing you want to do is get a self adhesive sheet of PEI. 220x220 should fit nicely - after you cut it to size :-)
About $10

Once you've got that - you won't need any glue or hairspray or tape. And I tried EVERYTHING on my original creator.
printbite is what fixed everything :-)
But cheap pei is almost as good.

Don't run it any faster than 70mm/s
Also print one of these: https://www.thingiverse.com/thing:537918
YOu'll need a 24v 40mm fan and a couple 3mm nuts and bolts.

And that's pretty much ALL the mods a replicator ever needs.
I also made my spool holders a lot smaller diameter - but that was because I had a few apols of odd stuff with 12mm holes. So used an adaptor and a couple 10mm bolts to replace the big plastic cylinders.

One of the most reliable 3d printers on the planet :-)
