Welcome back! You've got a bunch of options for getting back into Amigas these days:
1. A vintage machine 500, 1200, 3000, etc)
2. Emulation with WinUAE or FS-UAE
3. An AmigaOS4 machine like the X1000, X5000, or SAM boards
4. MorphOS, a ground-up rebuild of AmigaOS for most PPC Mac hardware
5. AROS, an open-source ground up rebuild of AmigaOS for x86 hardware and a few others
6. An FPGA hardware emulation board. These are mostly intended for games at the moment.
MorphOS and AROS probably have the best web browser situation on the Amiga-like platforms these days, but progress is being made for the vintage machines and OS4 as well.
For word processing, there are the old classics Wordworth and Final Writer. OS4 has a program called CinnamonWriter and there's something available on MorphOS, the name of which escapes me.
For network drives, there's smbfs for Windows-style SMB shares. A Dropbox handler is in development but I haven't tested it yet.
Printing is going to be tough. HP JetDirect printing works if you have a corresponding printer driver. Your safest bet will be something that supports PostScript. The network printer interfaces might support a few other protocols as well, but I'm not certain.
Don't be afraid to ask questions - the gang here will help you get going!
