Run Faster is also not a bad purchase if looking for more character options... but it is crunchy
Run Faster offers quite a lot of new qualities, some of which open up some interesting possibilities. It also adds race sub-variants, which some people love and some people really don't. Also it has some rules for more detailed lifestyles. All of that IS crunch, in a sense, but not the sort of crunch that shows up during missions much. Up to you if that adds to your game, or just overwhelms with options.
Depending on where you want to put your game, Hard Targets has some information about Havana.
Market Panic has updated status for the big 10 Megacorporations. I found it a bit disappointing, but still there is a lot of information in there should you wish to have deep corporate based plots.
Oddly enough, if you want to run a more street level campaign, Data Trails can be useful. It gives ways to get attack and sleaze ratings onto devices that don’t normally have them, hence allows tricks in the ‘trix without having actual cyberdecks (granted, low attack and sleaze ratings, but enough to deal with lower end home security or dealing with the cameras at Stuffer Shack, hopefully). Also rules for scavenging electronics for building things, which could be interesting in a low resources game.
