Don't train your own pokémon too high when you're afraid of Red's high lvled pocket monsters. If you can defeat Gary (Blue), the way to Red is open. You can easily beat him with fifties, although it's wise to get some TM's. Remember: in this case Pokémon is merely about brute force, without strong moves you're not going to survive. Red will not laugh with you, but laugh at you when you use quick attack against his Snorlax. If you can't afford good TM's, always make sure there's a lot of difference between the moves your pokémon have.
-Zap Cannon (vs Blastoise) -- Get it at the Power Plant.
-Hydro Pump (vs Charizard)-- Train a pokémon like Gyarados that learns it, or just the easy way: Lugia.
-Earthquake (vs Pikachu) -- Find it at Victory Road.
-Trash (vs Espeon, Snorlax) -- Nidoking (get a Moon Stone on Monday Night near Brock's Town) or Gyarados learn it (both powerful pocket monsters). Use this to rampage like hell.
-Aeroblast, Sky Attack, Fire Blast etc (vs Venusaur) -- Get a Lugia, Trade from R/B/Y or get it at the Game Corner. Flying/fire is very effective against Venusaur.
Yesterday I tried to complete Pokémon Silver in 24 hours of playing as a veteran without pause. After I beated the Elite Four, I had the following Pokémon without gameshark or cloning or whatever:
-Dragonite lvl 50
-Red Gyarados lvl 50
-Typhlosion lvl 50
-Sudowoodo lvl 50
-Lugia lvl 40
In one hour, I completed whole Kanto. My 5 pokémon were all lvl 55. Now I was permitted to catch either Ho-oH or to go and beat Red. I chose for Red, and in 5 minutes I hiked down the mountains to visit Red. It's quite possible to beat him with ''low'' lvls, without items. This was the strategy:
-Typhlosion used Earthquake against the 81 weak pikachu, one hit KO.
-Red Gyarados used Trash (2 hits) against the Espeon, which was quite hard compared to the others.
-Dragonite used Zap Cannon to destroy Blastoise in 1 hit.
-Snorlax (hardest, as everyone knows, lvl 75) was beaten by my Sudowoodo's Rock Slide (!) in 5 turns. Use big force to defeat this punk, every ''veteran'' knows the power of Rest-Snore-Body Slam etc.
-I accidentally forgot to switch when Venusaur came up, and he finished my Sudowoodo with his Solarbeam. I just chose Lugia and finished Red's weakest pokémon (after Pikachu) with just one Aeroblast. -Charizard didn't survive a one hit KO Hydro Pump.
I hope this helps for rookies (I don't think this game still has any) who don't have much time to train or veterans who, when they start a new game, want to make a speed record of finishing the whole game.

* If you have more time and want to make it slightly easier to defeat Snorlax, you could train a Ditto to lvl 50 and make it transform. I always used a lvl 30 ditto against the Elite Four in pokémon yellow.
