Never ever rush last whisper. Its not worth rushing as the enemy barely has any armor. Your 40% armor pen will penetrate about 10-15 armor at max.
The generic ranged ad build at the moment.
Boots 3 pot > IE + vamp scepter > Phantom Dancer > Blood thirster or last whisper > whichever item you didnt finish before > GA, QSS, or FMallet. Get Bezerker grieves when you think you need it. Usually during the IE + vamp scepter stage. The last whisper buy is when your enemy starts stacking armor. The defensive item can be bought right after your 3rd core item if the enemy is diving you every team fight.
The AD runes are questionable to say the least, ARP show much better returns imo...also generic Ranged AD build is varied depending on lane, if mid for some reason go with a Dorans first, if bot or top with a Support go Dorans, if Bot or Top without a support go Boots and Pots then pick up a Dorans or 2 and transition into a BF sword depending on how your lane is going.
BF > Vamp > BT > Zeal > BF > Inf Edge > Phantom > Then move into your last few items that are based solely on the opponents item builds.
Edit: As a point of reference the Dorans can and will be sold when your getting close to buying your first BF, so say you buy a Dorans then Boots, then another Dorans, obviously around 1400'ish gold you should sell the second Dorans and get your BF, also never just automatically buy Greaves, look at who you're facing in your lane, say you get Garen/Taric bot, instead of buying the mspeed boots you should probably look at getting the MR/Tenacity boots, if facing a heavy AD champ look at getting the +arm boots. Items should always be bought based on what you're facing especially boots. BF/IE/PD are what are called Core Items, every build should have them for Ranged AD carries. But Boots and anything after those 3 are really situational.
Decent guide for Trist, give it a looksie.
