New member with a few questions

Hi All!

I've finally created an account here, but am a proud owner of an 04 SR5 4x4 since new. It's been my only reliable transportation with all of the other project cars, and want to keep it as such.

Few questions now that I'm approaching 150k that I might need help with.
1) Timing belt
I replaced my original at around 75K. I assume I should probably do it now along with new plugs, etc. Any other service items at this point I should take a look at? The clutch for the manual is fairly new

2) Brakes
I tow with a ~1500# double axle trailer for a few small project cars (70-80s bmws and small euro classics), combined with a tekonsha brake controller. The brakes are horrible when towing and I'm avoiding doing any more until I upgrade. I did some quick searching and came across this:

Anybody with feedback on this for towing specifically? I have no wheel / suspension changes.

3) Suspension
I need to replace ball joints / tie rods soon as well. Are there any good tools / sources for them? Most of my equipment is for passenger cars, and not sure if I needed anything more heavy-duty.

Looking forward to the great new forum!
Cheers
