You are sure you have tubulars? In anycase, tubulars are usually called 28", they have essentially the same diameter as a 700c clincher. Yes tubulars require glue and patience. You can get tires at your local high end LBS or on the internet... try biketiresdirect.com, their prices seem good. Yellow jersey sells really cheep tubulars just labelled servizo course and people on this forum have said they are of decent quality.
