Ok, should I hop on a good deal for a flight from SFO to Paris RT for a total of 408 bucks and then work out the eurostar or easjet issues later about trying to do a two day visit of london?

i am thinking that i will be able to work out the eurostar issues with some help. But just not be able to book anything right now.

Your advice is so much appreciated.

Book the good deal now and work out the rest when you can. Long pole in the tent first.

$408 is definitely a good idea! What airline and what month?

Are you sure that's a round trip fare? Sometimes they quote one way fares based on RT to make it sound cheaper. If that is RT, does it include taxes and fuel surcharges? $408 RT sounds a bit too good to be true from SFO. If it is true, you'd better grab it before it's gone.

Grab it, assuming that includes taxes, 9/11 security charge, all other extras.
What airline, when?
that will be useful info for others

If it's for real, grab it! Tell us about the deal, please.

From Paris you might want to pre-book the EuroStar to London, less hassle, same time or less, and often cheap if you book early and keep it flexible.
