Wally, You said your friend is supplying a sugino 75 crankset, and mentioned 1/8" chain.
Though regular road chains, rings and cogs are fairly forgiving with respect to chain line (as others have noted), 1/8" track stuff can be more finicky. I have an 1/8" sugino ring and a 1/8" euro asia cog on my SO. I found I needed to have them lined up really well for things to run smoothly. I ended up getting a PW bottom bracket so I could easily fine tune the crank offset to match the cog (note: you really really want two of those lock ring tools to install a PW bottom bracket). That said i don't think any freewheels use 1/8" inch cogs so I'm guessing you are going to have a road width cog and that should be more forgiving. You could also pick up a road width chainring and just avoid any 1/8" stuff. Since that sugino 75 crank may not sit on the bottom bracket at the same offset as your current crank, you may want to mount it on your current bottom bracket and see how things line up (or don't) before picking a length for a new PW bottom bracket. Since you are thinking of moving things further from the center line, you aren't going to have clearance problems at the crank end. Take a quick look at the rear wheel and make sure you have a bit more than an 1/8" clearance (1/8" is ~3mm) between the chain and the seat stay. I suspect you will be fine there too.
