you got one with extra nice paint (Orange Pro is a grail frame for most Acer-Mex fans) plus this has original decals in 'good' condition plus the chrome stay caps that they didn't come out with until "later years"...so i think it already looks cool!
my 2 cents: I'd keep things original, maybe replace the Columbus decal but then just some cleaning and minor touch-up, then give it a good coat of wax...

Trivia note: I didn't recall them having just 2 TT cable guides when the Pro started coming with those brazed on: a nod to Colnago , maybe?
Trivia question: does it have a 27.2 seatpost or a smaller size?
