This whole case hinges on the fact that Ross Ulbricht = Dread Pirate Roberts. All of the government's evidence claims Ulbricht ran Silk Road and he's the person who ordered several assassinations. All they know is the person "known as" Dread Pirate Roberts did these things, so they need to tie DPR directly to Ulbricht.
Therefore, if the servers were searched illegally, then whatever was on those servers is important to Ulbricht, which means they're important to DPR, which then the government can tie the two together and make the direct relationship between them. This means even if he wins the Silk Road case, the government have established him as DPR and then can formally charge him under the several indictments they have for the murder for hire scheme.
If he doesn't challenge the search of the servers, and maintains since he's not DPR, then he has no stake in the evidence on those servers, then all the evidence (fairly strong circumstantial evidence) would stand and the government will most likely get a conviction since even though they haven't tied him directly to the DPR persona, all the evidence from the servers and other circumstantial evidence points directly to him. I say "most likely" but you never know for sure in these cases.
Contrary to what you believe, getting evidence thrown out in one case, actually solidifies the evidence in the other case. Also, it's likely the government is preparing their case to be ready to charge Ulbrict depending on what happens in the SR trial. Since Grand Jury's are a closed affair (defendants and their attorneys are not present) it's a dry run for the prosecution to see how strong their case is. They could be sitting on additional information, or still in the process of collecting more evidence against Ulbricht, you never know. There's a LOT we the general public won't know about their case until they actual charge him and have to start providing the evidence they have.
As for your other points, they're moot.
