Squeaky suspension/bushings?

I've got a 2000 Tacoma 4x4 with v-6. Love the truck, bought it used and it's completely stock/no mods (yet).
When getting in/out of it, you can hear squeaky stuff going on, sounds like the rubber suspension bushings or something?
Not sure how to isolate the sound but figure you guys would know what I'm talking about?

If this is the case, where's the best place (online) to buy a set of bushings from and is this a DIY job? I've got shop space, big air compressor, floor jacks, tools, etc. and am a fairly handy guy, not a mechanic by any means, but can manage with timing belt changes, brakes, stuff like that.

Thanks-Jim
This is a great site

 

On my truck its the wraps around the leaf springs that squeak. I sprayed lube on to get rid of it.

 

I'll give it a try-thanks!

 

most people say it is the friction pads on the leafs mine did it and i just spray bombed the leafs, pads, bushings any thing i thought mite be squeaking and that worked. it was silicone grease but i put a 6 inch lift on my truck and havnt had to do anything yet no squeaks yet
