Re: 17" wheels
275/40/17s should have the same diameter as the stock wheels. so there is no need to fix the speedo.
since you have an obd1 computer you can get a cable and connect it to a laptop or desktop (if you can get it close enough) and use free software to read the codes and sensor info.
some parts stores use to scan for free. call around

A Hypertech Power Programmer will let you adjust for tire diameter .25" at a time but is limited for engine programming for the price ($325). The cable/laptop/software option is the best for adjustability of engine parameters. The cables are around $70 last time I checked and if you have a laptop or can borrow one would be great. Search for LT1Edit for more info.
Advance Auto Parts and Auto Zone are two chains that will scan codes for you for free, though there's no guarentee the scanner will work. . . I had my 2000 Zr2 Blazer scanned one day and the code cleared. When the SES light came back on 4 days later, I replaced a simple part that may have been the cause (gas cap) and asked them to scan and clear the code. The guy couldn't get the reader to work and blamed it on the truck.
