All those are great options. Satellites are a blast to work with an HT and a dual-band Arrow handheld.
Probably what would be most useful is to build up confidence with the radio and your on-air acumen. Listening in on all the nets you can is helpful, but being a wallflower does not build much skill. Check in and get your name added to the roster. It does not take long before you become an old hand at that, plus you connect with hams who can either meet up and help you or help you over the air. Look up the call signs you hear on QRZ.com. Some may have profiles showing what they are doing with ham radio, and some of those things might look very cool to you. Those people could be your next Elmers.
Get a repeater list for your area. Practice plugging in the frequencies and see if you can hear any traffic. Next, practice setting the PL tones and offsets and see if you can transmit and be heard by the repeaters. Google the repeater callsigns to see if they are owned by clubs that may have web pages. Club websites almost always list nets. Listen to every net you can.
Maybe tune the radio to 144.390 and see if you hear any APRS traffic. You will, in less than a minute or two. Download AGWTracker/AGW Packet Engine and see if you can decode the screeches with your computer's microphone. Compare what you hear to what you see on http://aprs.fi
. Tune to 145.010 and see if you can hear any packet radio traffic. AGWPE can decode that as well.
Definitely go to the hamfest. Connect with clubs in your area, and attend their meetings. This is your best source of knowledge, real-world contacts, and likely your best source of 2nd-hand gear. I was handed a Yaesu G-5500 Az-El rotor because I had an interest in satellite work and a Yaesu FT-1000 just for being in the right place at the right time. Both were gear SKs had donated had donated to the club.
It's a mighty big world out there, and there has never been a better time to get into amateur radio. But don't try to figure it all out at once. It is a bigger and more diverse hobby than just about any other you can imagine.
