Is Skill Focus: Telepathy a valid feat choice? +3 to all Telepathy checks?
No, 'fraid not. They spotted that one, it's explicitly not allowed in the rules! I'd say the same for any "+2 to two skills" variant that includes Telepathy too.

Oh oh, and are the mechanics patterened after d20 Modern rules? I assume so, but it's good to be sure
Nnnno, I don't think so. I'm not that familiar with d20 Modern, but B5 uses vocation-based classes rather than ability score based classes plus professions.
Other specific variants to B5 d20:
You get a Defence Value based on class/level plus Dex. Armour counts as Damage Reduction.
Hit points are rare - combat tends to either be fist-fights or, if the PPGs come out, ducking for cover and hoping for the best.
Vehicle and Spacecraft combat is covered by almost a mini-game within the game, rather than being a direct conversion of interpersonal combat (Star Wars d20, I'm looking at you). Elements are the same (roll d20 plus attack modifier against defence value), but it allows more for tactical decisions and it also means you don't need to roll for every pulse cannoon on a battleship.
Some skills are combined (Notice, for example, is Spot and Listen), but most things are the same as in standard d20.
Influence is a subsystem that uses 3d6 + influence score to get favours from a particular group, from a loan, information, diplomatic pressure to the use of a war fleet (that one has a DC of something like 45).
I think there are a few specific rules relating to firefights, such as autofire, aiming and being pinned by enemy fire, but they'll come up as and when. Otherwise it's pretty much the same as other d20 games.
