Can't see the signature link from my tablet, but I believe your new system is Ascend. You really don't need a separate amplifier, any decent AVR will power those speakers adequately. Now if you have money to burn, that's a different story.
IV never used an amp before but wanted to one with my new speakers( listed below) where do I start?
Actually implement your equipment list as stated with the possible upgrade of an AVR with Audyssey (Onkyo, Denon).
Its not precisely what I'd choose, but it does look pretty good. Its not going to be a waste of money.
If you wanted to throw more money at the project after the AVR upgrade, next on your list should be your subwoofer. What you've got looks good but its hard to overspend on subwoofers.
Then there are the acoustic room treatments, which would probabaly be a good idea.
Most audiophiles are well served by AVRs in the 80-110 wpc range. One reason is that if you work out the typical peak SPLs, power levels, distances, etc., 50 wpc is all you need unless you want to accelerate your own ear damage, or buy equipment for the sake of buying equipment, even if you are already a little deaf. ;-)
