PSP Slim Homebrew Help

Please help me. I intend to homebrew my PSP Slim next week, and have a few questions about homebrew. I plan on using IR Shell 5.0, and installing LEDA. What i want to know is, will eLoader v1.000 work with 1.5 homebrew, which LEDA doesn't? The homebrew i wish to intially run are :

• Trigonometery Wars
• Jelly Car
• Squarez
• Ultimate PSP Tube
• Super Tux
• Ragdoll Cannon

I know some will launch without LEDA or eLoader, but will i be able to launch them all with a combination of the two? Also, for 1.5 homebrew, i notice there are two eboots, one in a folder with a % in front and one in a folder without. Which is it i should launch? Please tell me what files i should launch how. Thanks for your help
