I'd say go for the OS3.9 upgrade, it includes Genesis TCP/IP stack, Aweb browser and whole bunch of other good stuff for your ol' Miggy. IMO that's all you need. Of course you have to have access to CD-ROM to install it.
I bought it right away when I got back from the Darkside and it's money well spent.
Of course you have keep some restrictions in mind, like AGA. I remember I used surf the web in gray when I had my A1200 back in 90's. It was a lot faster and better looking than 64/128/256 colour screens.
But long story short, get the OS upgrade.
Good luck with your project and don't be lured by the Darkside.
