Baseline 2008 TC250 Suspension Settings?

Anyone out there have a good baseline suspension set-up for MX? I've left the suspension well enough alone for the break-in period but I've got about 12hrs on the bike now and find I'm taxing the suspension on the bigger hits and through the whoops. I suck at bike set-up in general, just hop on and ride so I need some help getting into the ball park. I have the forks at the stock settings, 15 clicks out for comp and rebound and went a bit stiffer on the rear, 10 clicks out for hi/low comp and rebound in order to get the rear end to not wallow through the fast rollers. Sag is 1" static and about 3.75 - 4" rider sag. To be honest, I haven't measured the rider sag fully geared up, just sat on it with street clothes and had my pops measure it, was 3.5" so I figure when I'm geared up it should be close.

My problems are the standard deflection on small bumps and bottoming badly on big hits. I'm about 175lbs, an aggressive rider, probably mid pack intermediate racer speed. The initial harshness isn't too bad, just forces me to ride aggressively and then it works well but the harder I push, the worse I blow through the stroke and bottom if I don't hit the down slopes perfectly. Since I'm old and just getting back into MX, I'm looking for a bit of forgiveness in the suspension so when I don't nail the jumps perfectly, I'm not scared for my life. There are a few big hits at the local track that I'm scared to hit with the given set-up since I fear a wicked harsh bottom and bounce out of control if I come up short or over jump ( the 110' table in particular I loose a ton of time rolling instead of jumping ). Need to have faith in the suspenders and grow some balls I suppose!

Thanks!
